Copula Modeling: An Application to Workers’ Compensation Claims

Public

Copulas are multivariate probability distributions used in the modeling of multiple random variables. In insurance, they are used to create models that preserve the relationship between a claim’s loss amount and any associated expenses, especially in large loss scenarios. The goal of this project was to develop a copula model for losses and their associated expenses and determine whether their use produces different results than current modeling methods. Through data analysis and simulation, the team identified that a copula model could be applied to claims in Workers’ Compensation. It was found that the copula model did not produce significantly different results than those produced using the sponsor’s traditional methods, validating their current models.
