Abstract

This study is a generalization of the length-biased and weighted Chris-Jerry distribution. It introduces an additional scale parameter to make the distribution more flexible. The functional form of the distribution which includes the density function, the distribution function, the survival function and the hazard function together with their plots were presented. The study also encapsulates the characteristics of the model with the estimation of the parameters using the maximum likelihood method. The applicability was demonstrated using data on remission times of a sample of 128 bladder cancer patients, mortality rate of children in Japan and Ireland under the age of five. The results validate that the model is apt in describing real life events.
