Generalized Weighted Rama Distribution: Properties and Application to Model Lifetime Data

Samuel U. Enogwe, Chisimkwuo John, Happiness O. Obiora-Ilouno & Chrisogonus K. Onyekwere · Asian Research Journal of Mathematics · 2021

In this paper, we propose a new lifetime distribution called the generalized weighted Rama (GWR) distribution, which extends the two-parameter Rama distribution and has the Rama distribution as a special case. The GWR distribution has the ability to model data sets that have posi...

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...
