Bayesian Analysis of FIAPARCH Model: An Application to Sao Paulo Stock Market

Thelma Safadi, Isabel Pereira

In order to study the inference problem we use the Metropolis-Hastings algorithm.This methodology is illustrated in a simulation study and it is applied to a set of observations concerning the returns of IBOVESPA values.
