Goodness-of-fit statistic, Lindley distribution, Maximum likelihood estimation


This paper corrects and updates Irshad et al. (2021) by some technical comments. The original paperwas inadvertently published with some errors, mainly the computational ones regarding the maximum likelihood (ML) estimate of the parameters of the fitted models which will be addressed and corrected in this paper. Furthermore, the standard errors of the ML estimates of different fitted models, as an important indicator of the accuracy of estimates and particularly are necessary for making the statistical inference for the population parameters, have been added.
