“…For more details on exponential distribution and its applications, [1] and [2] offer a useful reference. Empirical Bayes estimators of exponential distribution parameters have been introduced by multiple authors, such as [3] and [4] to support the generation of this function. [5] also investigated the use of the power function distribution as a conjugate prior to the estimation of the parameters required for the exponential distribution, while [6] used a prior drawn from the gamma to assess Bayesian estimation of the exponential distribution, applying the maximum likelihood estimator and three different loss functions to estimate the parameters of the exponential distribution.…”

In this paper, the estimators of the scale parameter of the exponential distribution obtained by applying four methods, using complete data, are critically examined and compared. These methods are the Maximum Likelihood Estimator (MLE), the Square-Error Loss Function (BSE), the Entropy Loss Function (BEN) and the Composite LINEX Loss Function (BCL). The performance of these four methods was compared based on three criteria: the Mean Square Error (MSE), the Akaike Information Criterion (AIC), and the Bayesian Information Criterion (BIC). Using Monte Carlo simulation based on relevant samples, the comparisons in this study suggest that the Bayesian method is better than the maximum likelihood estimator with respect to the estimation of the parameter that offers the smallest values of MSE, AIC, and BIC. Confidence intervals were then assessed to test the performance of the methods by comparing the 95% CI and average lengths (AL) for all estimation methods, showing that the Bayesian methods still offer the best performance in terms of generating the smallest ALs.
