On Hyperbolic Monomolecular Growth Model in Height/ Diameter Growth of PINES

Angela Unna Chukwu & Samuel Oluwafemi OYAMAKIN · Journal of Advances in Mathematics and Computer Science · 2015

This paper proposed a hyperbolic monomolecular growth model (HMMGM). The stabilizing parameter θ was introduced into the existing growth equations using a hyperbolic sine function given by. The reparametized equation namely, Hyperbolic Monomolecular Growth Equation, which was sol...

The Characterization of the Cubic Rank Inverse Weibull Distribution

Adebisi Ade Ogunde, Angela Unna Chukwu & Samuel obi-Nnamdi Agwuegbo · Asian Research Journal of Mathematics · 2020

This work provides a new statistical distribution named Cubic rank transmuted Inverse Weibull distribution which was developed using the cubic transmutation map. Various statistical properties of the new distribution which includes: hazard function, moments, moment generating fun...

The Marshall-olkin Inverse Lomax Distribution (MO-ILD) with Application on Cancer Stem Cell

Obubu Maxwell, Angela Unna Chukwu, Oluwafemi Samuel Oyamakin & Mundher A. Khaleel · Journal of Advances in Mathematics and Computer Science · 2019

A new compound distribution called the Marshall-Olkin Inverse Lomax distribution (MO-ILD) was proposed, extending the inverse Lomax distribution by adding a new parameter to the existing distribution, leading to greater flexibility in modeling various data types. Its basic statis...

Bayesian Analysis of a Shape Parameter of the Weibull-Frechet Distribution

Terna Godfrey Ieren & Angela Unna Chukwu · Asian Journal of Probability and Statistics · 2018

In this paper, we estimate a shape parameter of the Weibull-Frechet distribution by considering the Bayesian approach under two non-informative priors using three different loss functions. We derive the corresponding posterior distributions for the shape parameter of the Weibull-...

On Making an Informed Choice between Two Lomax-based Continuous Probability Distributions Using Lifetime Data

Terna Godfrey Ieren, Samuel Oluwafemi OYAMAKIN, Abubakar Yahaya, Angela Unna Chukwu, Adamu Abubakar Umar & Samson Kuje · Asian Journal of Probability and Statistics · 2018

Probability distributions and their generalisations have contributed greatly in the modeling and analysis of random variables. However, due to the increased introduction of new distributions there has been a major problem with choosing and applying the right distribution for a gi...
