The Dynamic Skellam Model with Applications

Koopman, Siem Jan; Lit, Rutger; Lucas, André - Tinbergen Instituut - 2014

We introduce a dynamic statistical model for Skellam distributed random variables. The Skellam distribution can be obtained by taking differences between two Poisson distributed random variables. We treat cases where observations are measured over time and where possible serial correlation is...

MODELING THE FREQUENCY OF CLAIMS IN AUTO INSURANCE WITH APPLICATION TO A FRENCH CASE

DAVID, Mihaela - In: Review of Economic and Business Studies (2014) 13, pp. 69-85

The aim of this paper is to present the different models for count data used in the actuarial literature. In addition to the Poisson regression, Negative Binomial and Zero-Inflated models are applied to an auto insurance portfolio of a French insurance company. Statistical tests to evaluate the...
