Uma abordagem clássica e bayesiana para o modelo de Tweedie
MetadataShow full item record
The goal of this work is to present a classic and a bayesian approach to the Tweedie Compound Poisson model considering the form and application shown at Jorgensen & Souza (1992). A speci.c goal is to estimate the individual claim mean values. Newton- Raphson iterative method is used in the classic inference in order to obtain the estimatives for the parameters. Non-informative priors are used to obtain the bayesian estimatives for the parameters. In the bayesian approach two di¤erent methodologies are considered: i) without the presence of covariance and ii) with the presence of covariance. The per- formance of both methods, classic and bayesian inference, are compared via simulated data.
