Power Samade distribution: its properties and application to real lifetime data

Abstract

A new three parameter lifetime distribution has been introduced in this research work by using Gamma generalized family of distributions. The density, survival, and hazard functions of the proposed Power Samade distribution were derived and discussed. Its mathematical properties were derived. The maximum likelihood method of estimation was used to estimate its parameters. Three lifetime data sets were used to assess the performance of the proposed distribution. Our finding revealed that the Power Samade distribution suited all the data sets compared to the other competing distributions as it has a maximum value of loglikelihood and least values of statistic criteria including AIC, AICC and BIC.
