On the Omission of Intercept Term in Model Estimation: A Monte Carlo Simulation Study
Abstract: AbstractThe issue of having an intercept term in linear regression model is an unsettled issue in the literature. It can be said that, generally, including the constant term depends on the research. But it must be known that the estimation of parameters differs according to involvement of the constant. If an intercept term exists in the model, the least squares estimate of the slope parameter will be unbiased. In this …

The Weibull Distribution: A Revisit
Abstract: AbstractWeibull distribution is the most popular model in modeling data from various fields. From its introduction, comprehensive work has been done on this model providing distinct interpretations, constructions, generalizations, inferential methods, discrete cases and extensions to bivariate and multivariate. More than 4000 papers have appeared describing all these aspects and developments. This paper provides a review on the historical background and parallel developments of the Weibull distribution. Further, various generalizations …

On Some Length-biased Distributions: An Overview
Abstract: AbstractThis paper review works on some length-biased distributions. The length-biased distributions received much attention in the literature since they occur naturally in many situations where it is not possible to work with a truly random sample from the population of interest. Some important length-biased distributions studied in the recent literature are length-biased versions of Inverse Gaussian, Log-normal, Beta Type I and Type II, Weighted Generalized Rayleigh and Birnbaum-Saunders distributions are …
