A Portfolio-Anchored Frequency-Severity Risk Index for Trip and Driver Assessment Using Telematics Signals

Jongtaek Lee, Andrei Badescu, X. Sheldon Lin

In this paper, we propose a novel frequency-severity joint trip-level risk index that combines the frequency of abnormal driving patterns with a severity component reflecting how e…

A Population Sampling Framework for Claim Reserving in General Insurance

Sebastian Calcetero Vanegas, Andrei L. Badescu, X. Sheldon Lin

Claim reserving in insurance has been studied through two primary frameworks: the macro-level approach, which estimates reserves at an aggregate level (e.g., Chain-Ladder), and the…

Assessing Driving Risk Through Unsupervised Detection of Anomalies in Telematics Time Series Data

Ian Weng Chan, Andrei L. Badescu, X. Sheldon Lin

Vehicle telematics provides granular data for dynamic driving risk assessment, but current methods often rely on aggregated metrics (e.g., harsh braking counts) and do not fully ex…

Claim Reserving via Inverse Probability Weighting: A Micro-Level Chain-Ladder Method

Sebastian Calcetero-Vanegas, Andrei L. Badescu, X. Sheldon Lin

Claim reserving primarily relies on macro-level models, with the Chain-Ladder method being the most widely adopted. These methods were heuristically developed without minimal stati…

A Marked Cox Model for IBNR Claims: Model and Theory

Andrei L. Badescu, X. Sheldon Lin, Dameng Tang

Incurred but not reported (IBNR) loss reserving is an important issue for Property & Casualty (P&C) insurers. The modeling of the claim arrival process, especially its temporal dep…
