Modelling dependence in a ratemaking procedure with multivariate Poisson regression models

Bermúdez, Lluís; Karlis, Dimitris - Xarxa de Referència en Economia Aplicada (XREAP) - 2010

When actuaries face with the problem of pricing an insurance contract that contains different types of coverage, such as a motor insurance or homeowner's insurance policy, they usually assume that types of claim are independent. However, this assumption may not be realistic: several studies have...

GEE type inference for clustered zero-inflated negative binomial regression with application to dental caries

Kong, Maiying; Xu, Sheng; Levy, Steven M.; Datta, Somnath - In: Computational Statistics & Data Analysis 85 (2015) C, pp. 54-66

Use of zero-inflated count data models is common in applications where the number of zero counts exceeds that predicted from a traditional count data model such as Poisson or negative binomial. When count data exhibiting inflated zero counts are correlated among subjects, a natural approach will...

Identification issues in some double-index models for non-negative data

Papadopoulos, Georgios; Santos Silva, J.M.C. - In: Economics Letters 117 (2012) 1, pp. 365-367

We highlight a subtle identification problem that afflicts models for non-negative data in which the conditional expectation is specified as the product of a logit and an exponential function. The results are illustrated with an empirical model for medical expenditures.
