Research Article
In any Bayesian inference problem, the posterior distribution is a product of the<br>
likelihood and the prior: thus, it is a ected by both in cases where one possesses little or no<br>
information about the target parameters in advance. In the case of an objective Bayesian<br>
analysis, the resulting posterior should be expected to be universally agreed upon by ev-<br>
eryone, whereas . subjective Bayesianism would argue that probability corresponds to the<br>
degree of personal belief. In this paper, we consider Bayesian estimation of two-parameter<br>
exponential distribution using the Bayes approach needs a prior distribution for parame-<br>
ters. However, it is dicult to use the joint prior distributions. Sometimes, by using linear<br>
transformation of reliability function of two-parameter exponential distribution in order to<br>
get simple linear regression model to estimation of parameters. Here, we propose to make<br>
Bayesian inferences for the parameters using non-informative priors, namely the (depen-<br>
dent and independent) Je reys' prior and the reference prior. The Bayesian estimation was<br>
assessed using the Monte Carlo method. The criteria mean square error was determined<br>
evaluate the possible impact of prior speci cation on estimation. Finally, an application on<br>
a real dataset illustrated the developed procedures.
