Effect of Predictive Variables on Insurance Claim Severity Estimates

Abstract

Insurance claim severity represents the financial amount associated with individual insurance claims and is an important component of actuarial analysis, pricing, reserving, and risk management. Accurate estimation of claim severity depends on the identification and appropriate use of variables that explain differences in claim amounts. Predictive variables such as policy characteristics, claim features, exposure information, and insured risk factors can therefore influence the reliability of estimated claim severity. This study will examine the effect of predictive variables on insurance claim severity estimates. It will assess how selected predictive variables influence the estimated monetary severity of insurance claims and determine which variables contribute to variations in claim amounts. The study will also examine how the inclusion or exclusion of relevant predictive variables affects the accuracy and stability of claim severity estimates. The study will focus on predictive variables, insurance claim severity, claim severity estimates, actuarial modelling, claims data, risk factors, policy characteristics, exposure variables, loss amounts, and insurance pricing. Statistical and actuarial techniques will be used to analyse relationships between predictive variables and claim severity and to develop models for estimating expected claim amounts. Probability distributions and regression-based methods may be applied to assess the contribution of individual variables to severity estimates. A quantitative research approach will be adopted for the study. Historical insurance claims data containing claim amounts and relevant policyholder, policy, exposure, and claim characteristics will be analysed using descriptive statistics, correlation analysis, regression analysis, probability distribution fitting, comparative analysis, model validation, and sensitivity analysis. Alternative sets of predictive variables will be incorporated into claim severity models to determine their effects on estimated claim amounts and model performance. The study is expected to reveal that predictive variables may have a significant effect on insurance claim severity estimates. Variables associated with policy characteristics, exposure levels, claim circumstances, and insured risk profiles may produce differences in estimated claim amounts when incorporated into actuarial models. The magnitude of the effect may depend on the relevance and quality of the predictive variables, the characteristics of the claims portfolio, the statistical distribution of claim amounts, and the modelling technique applied. The study will be useful to actuaries, insurance companies, underwriters, pricing analysts, claims managers, financial analysts, regulators, and researchers. It may provide useful information for improving claim severity estimation, strengthening insurance pricing and reserving practices, identifying relevant risk characteristics, and enhancing actuarial model performance. The findings may also assist insurers in selecting appropriate predictive variables for estimating potential claim costs. The study concludes that predictive variables are important considerations in estimating insurance claim severity because differences in risk and claim characteristics can influence the expected amount of individual claims. It is therefore recommended that insurers use relevant and reliable predictive variables, regularly validate claim severity models, and assess the sensitivity of severity estimates to changes in selected variables to support accurate actuarial pricing and claims management.
