Estimating the Scale Parameter for the Lindley Distribution - A Comparative Study of Waiting Time Analysis


This research deals with estimating the scale parameter for Lindley distribution by using the maximum likelihood method (ML) and standard Bayes method (SB), then a comparison was done between these estimators depending on the mean square error (MSE) criteria which depends on different simulation experiments . The results proved the priority of Bayes estimator when the samples sizes was small , vice versa in the case of medium and large samples size. The best estimator was invested for studying and analyzing the waiting time for AL-Rasheed Bank / AL- Mustansiriya University clients
