Inverted Power Ishita Distribution and Its Application to Lifetime Data

A. Omoruyi Frederick, George A. Osuji & Chrisogonus K. Onyekwere · Asian Journal of Probability and Statistics · 2022

In this paper, a new distribution, named ‘the Inverted Power Ishita distribution’, was introduced.  It is an extension of the Ishita distribution and its capable of modelling real life data with upside down bathtub shape and heavy tails was introduced. Mathematical and statistica...

Generalized Inverse Power Sujatha Distribution with Applications

O. Michael Okoli, George A. Osuji & Chrisogonus K. Onyekwere · Asian Journal of Probability and Statistics · 2021

In this paper, we present a new lifetime distribution known as the generalized inverse power Sujatha distribution. The statistical and mathematical properties of the new distribution such as the moment and moment generating function, Renyi entropy and distribution of order statis...

Inverted Power Rama Distribution with Applications to Life Time Data

Chrisogonus K. Onyekwere, George A. Osuji & Samuel U. Enogwe · Asian Journal of Probability and Statistics · 2020

In this paper, we introduced the Inverted Power Rama distribution as an extension of the Inverted Rama distribution. This new distribution is capable of modeling real life data with upside down bathtub shape and heavy tails. Mathematical and statistical characteristics such as th...
