INTRODUCTION
The frequency and severity of insurance claims are important factors that affect the pricing of premiums and the profitability of insurers.Frequency refers to the number of claims that an insurer expects to receive in a given period, while severity refers to the average cost of each claim.Both frequency and severity can vary depending on the type of insurance, the characteristics of the insured, and the external environment.One example of insurance claims in a developed economy is the US life insurance market, which saw a record-high premium of US$15.3 billion in 2021, driven by strong growth in the first quarter due to the COVID-19 pandemic.However, sales slowed down in the second half of the year due to consumer concerns over inflation and the economy.The frequency of claims also increased as more policyholders died from COVID-19 or other causes, while the severity of claims decreased as insurers paid out lower amounts due to lower interest rates and mortality improvements (Anapapa, 2020).Another example is the Japanese non-life insurance market, which faced challenges from natural disasters, such as typhoons, floods, and earthquakes, in recent years.These disasters caused a surge in both frequency and severity of claims, especially for property and casualty insurance.For instance, in 2019, Japan experienced 21 typhoons, which resulted in about 1.6 million claims and a total payout of JPY 1.66 trillion (about US$15 billion).To cope with the rising claims costs, insurers have increased their premiums, diversified their products, and enhanced their risk management.
A third example is the UK motor insurance market, which has been affected by changes in regulation, technology, and consumer behavior.The frequency of claims has declined due to factors such as improved road safety, reduced traffic volume, and increased use of telematics devices.However, the severity of claims has increased due to factors such as higher repair costs, higher personal injury awards, and higher fraud rates.For instance, in 2020, the average cost per claim rose by 8% to GBP 4,600 (about US$6,300), while the total number of claims fell by 19% to 2.1 million.
In developing economies like Rwanda, insurance claims frequency and severity trends are shaped by the country's unique economic and social characteristics.Rwanda has been making significant strides in expanding its insurance sector and improving access to insurance products.According to a report by the National Bank of Rwanda (NBR) on the insurance sector in Rwanda (NBR, 2020), the frequency of insurance claims in the country has been influenced by factors such as healthcare accessibility and agricultural activities.For instance, the availability of micro insurance products has led to an increase in health insurance claims as more people gain access to medical services.The severity of insurance claims in Rwanda is also subject to various factors.The NBR report highlights that the severity of claims in the country can be influenced by the limited financial resources of the population, which can affect the extent of coverage and the size of claim payouts.Additionally, natural disasters such as flooding and droughts can lead to significant agricultural insurance claims, impacting the severity of claims within the agricultural sector.
In developed economies such as the United States, insurance claims frequency and severity trends have been influenced by various factors over the years.According to a study published by Smith, (2018) the frequency of insurance claims in the USA has been on a declining trend in recent years due to improvements in safety measures and risk management practices.For example, in the property and casualty insurance sector, the frequency of auto accident claims has decreased steadily due to advancements in vehicle safety technology and stricter traffic regulations.In contrast, the severity of insurance claims has exhibited an increasing trend, primarily driven by rising medical costs and repair expenses.For instance, the cost of healthcare in the USA has been steadily climbing, leading to higher medical claim payouts.
In developed economies like Japan, a similar trend can be observed.A study by Nakamura and Yamamoto (2017) found that insurance claims frequency has remained relatively stable in Japan, with minor fluctuations attributed to natural disasters like earthquakes and typhoons.However, the severity of insurance claims has increased due to the aging population, leading to higher healthcare costs and long-term care expenses.This demographic shift has placed substantial pressure on the Japanese insurance industry to provide adequate coverage and manage the growing severity of claims.
In developing economies, the frequency and severity of insurance claims can exhibit different patterns due to unique socioeconomic factors and varying levels of insurance penetration.For example, in India, a study conducted by Mishra and Chakraborty (2019) reported a rising frequency of health insurance claims driven by increased awareness and accessibility to healthcare services.However, the severity of claims in developing economies like India tends to be lower compared to developed economies due to lower healthcare costs and lower income levels, which influence the type and scope of insurance coverage available to the population.
In developing economies such as India, China, and Brazil, the frequency and severity of insurance claims exhibit unique characteristics shaped by the economic, social, and regulatory environments.For instance, in India, a study by Sharma et al. (2018) highlighted a rising frequency of motor vehicle insurance claims, mainly attributed to increased vehicle ownership and road traffic congestion.This trend is consistent with rapid urbanization and the expanding middle class, which has led to greater automobile usage.
On the other hand, the severity of insurance claims in developing economies can be influenced by factors such as infrastructure quality and labor costs.For example, in China, a research paper by Li and Wang (2016) revealed that property insurance claims related to construction projects have shown increased severity due to higher construction material costs and labor expenses.China's booming construction industry and urbanization drive have contributed to these dynamics.
In Brazil, a study conducted by Silva and Santos (2019) reported varying trends in insurance claims depending on the type of coverage.While the frequency of auto insurance claims has increased due to rising traffic accidents, the severity of health insurance claims has also been on the rise due to escalating healthcare costs.Brazil's complex socioeconomic landscape and evolving insurance market contribute to these distinct patterns.In developing economies, the interplay of economic growth, infrastructure development, and regulatory changes can significantly impact the frequency and severity of insurance claims.These countries often experience rapid changes in risk profiles as they undergo economic transformation and urbanization, making it essential for insurance companies to adapt to emerging trends.
In Sub-Saharan African economies, insurance markets are still in nascent stages of development, with limited data available on trends.However, some studies suggest that insurance claims frequency and severity may vary widely across the region, influenced by factors such as political instability, natural disasters, and access to insurance products.Further research is needed to provide a comprehensive analysis of insurance claims in Sub-Saharan Africa.The landscape of insurance claims exhibits significant variations across countries due to diverse economic, political, and social conditions.While limited data is available, some trends can be observed.A study by Adeoye and Ajiboye (2017) suggests that the frequency of insurance claims in Sub-Saharan Africa is affected by factors such as agricultural dependence and vulnerability to natural disasters.For instance, countries with predominantly agrarian economies may experience higher claim frequencies during adverse weather conditions or crop failures.Regarding the severity of insurance claims in Sub-Saharan Africa, it is influenced by factors such as healthcare infrastructure and access to financial resources.In countries with limited healthcare facilities and lower income levels, the severity of health insurance claims may be lower compared to developed economies due to reduced medical costs.However, the severity of claims related to natural disasters or political instability can be significant in some regions.
Insurance policies are contracts that specify the terms and conditions of the coverage, the premium, the deductible, the exclusions, and the benefits.Various insurance policy attributes can affect the frequency and severity of insurance claims, which are the requests for compensation from the insurer by the policyholder or a third party.Various insurance policy attributes play a crucial role in shaping the dynamics of insurance claims, particularly in terms of their frequency and severity.One essential attribute is the policy coverage limit, which defines the maximum amount an insurer will pay for a covered loss.Insurance policies with higher coverage limits tend to experience lower claim frequency but potentially higher claim severity.This is because policyholders may be more cautious about filing claims for smaller losses when they know they have substantial coverage.Conversely, policyholders may be more inclined to file claims for larger losses when they have higher coverage limits, resulting in increased severity (Harrington,2016).
Deductibles are another critical attribute.They represent the amount the policyholder must pay out of pocket before the insurance coverage kicks in.Policies with higher deductibles typically exhibit lower claim frequency but may have lower severity as well.This is because policyholders are less likely to file claims for smaller losses when they bear a significant portion of the initial cost.On the other hand, lower deductibles can lead to higher claim frequency, especially for minor incidents, but potentially lower claim severity as policyholders are more willing to claim when the out-of-pocket cost is minimal.These policy attributes highlight the delicate balance insurers must strike to manage their exposure to both frequency and severity of claims effectively (Doherty & Dionne, 1993)

Problem Statement
Predictive modeling of insurance claims is a technique that uses statistical methods and machine learning algorithms to estimate the probability and amount of future claims based on historical data and other factors.This technique can help insurance companies to optimize their pricing, underwriting, and risk management strategies, as well as to improve customer satisfaction and retention.However, applying predictive modeling to insurance claims in Rwanda poses several challenges, such as data availability and quality, regulatory and ethical issues, and cultural and social factors.In this paper, we review the current state of predictive modeling of insurance claims in Rwanda, identify the main challenges and opportunities, and propose some recommendations for future research and practice Mukamana & Niyonzima, (2020).The research gap in this context lies in the scarcity of studies that investigate and develop predictive modeling techniques customized for the Rwandan insurance landscape.Existing literature primarily focuses on predictive modeling in more developed insurance markets, leaving a notable void in understanding how these techniques can be adapted to the unique socio-economic and healthcare conditions of Rwanda, thereby hindering the industry's capacity to optimize claims management and pricing strategies in the country.

Actuarial Science Theory
Actuarial science is a field of study that focuses on assessing and managing risk, particularly in the insurance and finance industries.The main theme of actuarial science is to use mathematical and statistical techniques to analyze and predict future events, such as insurance claims.It originated from early work by mathematicians and actuaries like Abraham de Moivre and Daniel Bernoulli.In the context of the suggested topic, actuarial science theory is highly relevant because it provides the mathematical and statistical foundations for predictive modeling in insurance, helping insurers estimate future claims and set appropriate premiums (Bowers, 1997).

Behavioral Economics Theory
Behavioral economics, pioneered by researchers like Daniel Kahneman and Amos Tversky, examines how psychological factors influence economic decisions.It explores how individuals may deviate from purely rational decision-making, often making decisions based on biases and heuristics.In the context of insurance claims modeling in Rwanda, this theory is relevant because it can help understand the behavioral factors that affect insurance purchasing decisions and claims behavior in a specific socio-economic and cultural context.It can inform the development of predictive models that account for these behavioral nuances (Kahneman & Tversky, 1979).

Economic Development Theory
Economic development theory, with contributions from scholars like Walt Rostow and Amartya Sen, explores the processes and factors that drive economic growth and development in countries.In the context of insurance claims modeling in Rwanda, this theory is relevant because it helps researchers understand the broader socio-economic context in which insurance operates.It can shed light on how economic development indicators, such as GDP per capita or income distribution, impact insurance claims patterns, and how insurance, in turn, can contribute to economic resilience and development (Sen, 1981).

Empirical Studies
Rukundo (2017) developed a robust predictive model for insurance claims in Rwanda, recognizing the significance of accurate claim predictions for insurers' risk assessment and management.The researchers gathered historical insurance claims data and employed a Random Forest algorithm, known for its predictive power and ability to handle complex data structures.Their findings revealed that the model achieved a high level of accuracy in predicting future insurance claims, thus demonstrating its potential to assist insurance companies in estimating their liabilities more effectively.In light of these results, the study recommended the integration of predictive modeling techniques into the Rwandan insurance industry, emphasizing the importance of leveraging such advanced tools to enhance risk assessment, pricing strategies, and overall decision-making processes in the sector (Rukundo, 2017).Ndikubwimana and Hagenimana (2018) conducted a comprehensive study focusing on the development of a predictive model for health insurance claims in Rwanda.Understanding that effective predictive models could revolutionize the health insurance sector by allowing insurers to set premiums based on individual risk profiles, they employed logistic regression as their chosen methodology.The study unearthed valuable insights, indicating that variables such as age, gender, and pre-existing health conditions significantly influenced the likelihood and patterns of health insurance claims.Building upon these findings, the study recommended the widespread adoption of predictive modeling techniques within the Rwandan health insurance landscape, highlighting the potential benefits for both insurers and policyholders.Such a strategic move would not only promote fairness and sustainability but also usher in a new era of evidence-based decision-making within the health insurance industry (Ndikubwimana and Hagenimana, 2018).Uwase (2019) emphasized the pivotal role that predictive modeling can play in managing risks associated with crop insurance in Rwanda.The researchers undertook the task of analyzing historical crop yield data and weather patterns, employing advanced time series analysis techniques.Their findings underscored the importance of incorporating weather-related variables into predictive models, as this significantly improved the accuracy of claim predictions.In light of these findings, the study recommended the widespread implementation of predictive models to assist both farmers and insurers in making informed decisions regarding risk management strategies and policies, thereby enhancing the resilience and sustainability of agricultural insurance in Rwanda.Mukandayisenga and Uwizeyimana (2016) With a specific focus on motor insurance claims, this research sought to develop a predictive model that could offer valuable insights into the factors influencing claim likelihood, enabling insurers to optimize premium pricing and minimize fraudulent claims.To achieve this, the researchers employed data mining techniques, particularly decision trees, and conducted an in-depth analysis of historical accident data and driver information.Their findings indicated that variables such as driver age, vehicle type, and accident history played a pivotal role in predicting motor insurance claims.Building on these findings, the study recommended the widespread adoption of predictive modeling techniques within the Rwandan motor insurance sector.Such an approach could not only lead to more accurate risk assessment and pricing but also foster transparency and trust among insurers and policyholders.Nsanzimana (2017) delved into the prediction of health insurance claims, with a particular focus on non-communicable diseases, which represent a significant portion of healthcare costs in Rwanda.Employing a Bayesian network approach, the researchers aimed to model the intricate relationships between various risk factors and health insurance claim outcomes.Their findings underscored the importance of early disease detection and prevention, particularly in the context of insurance policies.The study recommended the proactive integration of predictive modeling techniques into health insurance to enhance the effectiveness of interventions, reduce healthcare costs, and ultimately improve health outcomes for policyholders.Hakizimana (2018) the study centered on the predictive modeling of property insurance claims in Rwanda, recognizing that the accurate assessment of location and property type could significantly influence claim frequency and severity.Researchers utilized geographic information system (GIS) techniques to analyze historical property data and gain valuable insights.The findings highlighted the potential benefits of GIS-based predictive models in assessing and pricing property insurance risks accurately.The study recommended the widespread adoption of GIS technology within the property insurance sector, underscoring the advantages of informed decision-making and risk management for both insurers and policyholders.Mugisha and Kambizi (2017) focused on the life insurance sector, this research aimed to develop predictive models that could assist in the estimation of reserves and pricing for life insurance policies in Rwanda.Actuarial methods were employed to analyze mortality data and life insurance policies, with particular attention given to factors such as age, gender, and policy duration.The findings indicated that these variables played a pivotal role in predicting life insurance claims.The study recommended the adoption of such predictive models within the Rwandan life insurance sector, emphasizing the potential benefits for insurers and policyholders alike.These models could enable more accurate pricing and policy customization, thereby fostering the growth and sustainability of the life insurance industry in Rwanda.

METHODOLOGY
This study adopted a desk methodology.A desk study research design is commonly known as secondary data collection.This is basically collecting data from existing resources preferably because of its low-cost advantage as compared to field research.Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries.

FINDINGS
The results were analyzed into various research gap categories that is conceptual, contextual and methodological gaps Conceptual Research Gap: While the studies by (Rukundo, 2017) and (Mukandayisenga and Uwizeyimana, 2016) focused on predictive models for insurance claims in Rwanda, specifically in the context of property insurance and motor insurance, respectively, there is a conceptual research gap in exploring the synergies and potential integration of these predictive models across different insurance sectors.Understanding how predictive modeling techniques employed in one insurance sector can inform and enhance models in others remains unaddressed.Such research would contribute to the development of a holistic framework for predictive modeling within the Rwandan insurance industry, facilitating knowledge transfer and cross-sectoral insights.
Contextual Research Gap: While several studies by Mugisha & Kambizi, (2017) underscored the importance of predictive modeling in various insurance sectors in Rwanda, there is a contextual research gap in investigating the specific challenges and opportunities associated with the practical implementation of predictive models.Understanding the barriers and facilitators in adopting these models within the Rwandan insurance landscape, such as regulatory frameworks, data availability, and industry readiness, is crucial.Such research could provide valuable guidance for policymakers and insurers in effectively harnessing the potential of predictive modeling in the local context.

Geographical Research Gap:
Although the studies by (Uwase, 2019) and (Hakizimana, 2018) delved into predictive modeling in the context of crop insurance and property insurance in Rwanda, respectively, there is a geographical research gap regarding the scalability and applicability of these models to other regions or countries with similar agricultural or property insurance needs.Investigating the transferability of these models beyond Rwanda's borders could contribute to the broader adoption of predictive modeling techniques in similar geographic contexts, fostering international collaboration and knowledge dissemination.

Conclusion
