As situações em que vários parâmetros populacionais precisam ser estimados simultaneamente surgem frequentemente em amplas áreas de aplicações, incluindo modelagem de confiabilidade, análise de sobrevivência e estudo biológico. Neste artigo, propomos métodos Bayesianos de estimativa dos parâmetros ordenados das duas populações exponenciais, que incorporam a informação anterior sobre a restrição de ordem simples, mas às vezes quebram a restrição de ordem. Um estudo de simulação mostra que os estimadores propostos são mais eficientes (em termos de erros quadráticos médios) do que a regressão isotônica dos estimadores de máxima verossimilhança com pesos iguais. Um exemplo ilustrativo é finalmente apresentado.

Abstract: The situations where several population parameters need to be estimated simultaneously arise frequently in wide areas of applications, including reliability modeling, survival analysis and biological study. In this paper, we propose Bayesian methods of estimation of the ordered parameters of the two exponential populations, which incorporate the prior information about the simple order restriction, but sometimes breaks the order restriction. A simulation study shows that the proposed estimators are more efficient (in terms of mean square errors) than the isotonic regression of the maximum likelihood estimators with equal weights. An illustrative example is finally presented.
