Gamma Generalized Power Lomax: A Novel Distribution in Modelling Covid-19 Data

Abstract

In this study, we developed a flexible form of Power Lomax distribution called Gamma Power Lomax distribution. This distribution was obtained by combining the Power Lomax and Gamma distributions to generates a novel life-time distribution with three parameters. Different structural characteristics of the new distribution have been determined and analysed which includes moments, moment generating function, order statistics, and incomplete moments. Distinct plots depict the behaviour of the density and the distribution function. The maximum likelihood estimation method was applied to estimate the distribution parameters. The practicability of the stated distribution is proven by Covid-19 data set. The objective of this study is to establish an optimum statistical model considering current covid-19 pandemic.
