Meta-Análise: Um Enfoque Bayesiano

Abstract in Portuguese
Apresentamos neste trabalho o uso de meta-análise sob um enfoque Bayesiano. Metaanálise se refere a métodos quantitativos que combinam resultados de estudos independentes para tirar conclusões gerais. Freqüentemente resultados de diferentes estudos são combinados de forma inadequada, resultando em uma análise inferencial não confiável. Métodos Bayesianos para meta-análise são preferíveis em vista do pequeno número de estudos que prevalecem em meta-análise. Para exemplificar o uso desta técnica, utilizamos alguns conjuntos de dados disponíveis na literatura e um conjunto de dados simulado. A análise Bayesiana foi possível devido a utilização de métodos de simulação de Monte Carlo via Cadeias de Markov.

Abstract in English
This work is concerned with the use of meta-analysis from a Bayesian point of view. Meta-analysis is a quantitative method combining independent results to obtain global conclusions. Frequently different results are combined unapropriately leading to an unreliable inferential analysis. Bayesian methods for meta-analysis are preferred due to the small number of experiments which are caracteristc of this technique. Sets of data taken from the literature, were used to illustrate the use of the technique, and a simulation set. A Bayesian analysis is made possible through the use of Monte Cano simulation methods via Marcos' Chains.
