Bayesian Estimation and Prediction of Discrete Gompertz Distribution

M. A. Hegazy, R. E. Abd El-Kader, A. A. EL-Helbawy & G. R. AL-Dayian · Journal of Advances in Mathematics and Computer Science · 2021

In this paper, Bayesian inference is used to estimate the parameters, survival, hazard and alternative hazard rate functions of discrete Gompertz distribution. The Bayes estimators are derived under squared error loss function as a symmetric loss function and linear exponential l...
