Título: Different Estimation Methods in Lifetime Models
Resumo:
This work presents different estimation procedures for the parameters of
lifetime models from both frequentist and Bayesian points of view. We
briefly describe different frequentist approaches, such as bias-corrected
maximum likelihood, method of moments, percentile estimators, L-moments,
ordinary least squares, maximum product of spacings and the maximum
goodness-of-fit estimators. Under the Bayesian inference the choice of the
prior distribution is often controversial, therefore, we discuss different
procedures to obtain objective priors under formal rules. Further, a simple
example is present to illustrate
that flat priors are not automatically non-informative; and non-informative
priors are not necessarily flat. Finally, these estimation procedures are
applied in some lifetime distributions.
Saudações,
Ricardo
