π€ AI Summary
This study addresses the growing complexity in residential insurance risk assessment driven by increasingly frequent extreme weather events, with particular emphasis on the pronounced impact of shifting precipitation patterns on insurance claims. The authors propose a novel two-stage modeling framework that, for the first time, integrates deep neural networks with Copula-based multivariate analysis to accurately capture the high-dimensional, nonlinear dependence structure between precipitation and insurance claims. By combining the powerful nonlinear fitting capability of deep learning with the flexible modeling of multivariate dependencies offered by Copula theory, the approach demonstrates significant predictive improvements when validated on empirical data from Canadaβs Prairie region spanning 2002β2011. This work advances a new paradigm for climate-related insurance pricing and risk management by substantially enhancing the accuracy of precipitation-driven risk prediction.
π Abstract
Extreme weather events are becoming more common, with severe storms, floods, and prolonged precipitation affecting communities worldwide. These shifts in climate patterns pose a direct threat to the insurance industry, which faces growing exposure to weather-related damages. As claims linked to extreme weather rise, insurance companies need reliable tools to assess future risks. This is not only essential for setting premiums and maintaining solvency but also for supporting broader disaster preparedness and resilience efforts. In this study, we propose a two-step method to examine the impact of precipitation on home insurance claims. Our approach combines the predictive power of deep neural networks with the flexibility of copula-based multivariate analysis, enabling a more detailed understanding of how precipitation patterns relate to claim dynamics. We demonstrate this methodology through a case study of the Canadian Prairies, using data from 2002 to 2011.
