Estimation in Step-stress Partially Accelerated Life Test for Exponentiated Pareto Distribution under Progressive Censoring with Random Removal

Amal S. Hassan, Marwa Abd-Allah & Hamdy G. A. El-Elaa · Journal of Advances in Mathematics and Computer Science · 2017

Accelerated life testing or partially accelerated life testing is generally used in manufacturing industries since it affords significant minimization in the cost and test time. In this paper, a step-stress partially accelerated life test under progressive type-II censoring with...

The Compound Family of Generalized Inverse Weibull Power Series Distributions

Amal S. Hassan, Salwa M. Assar & Kareem A. Ali · Current Journal of Applied Science and Technology · 2016

Compounding a continuous lifetime distribution with a discrete one is a useful technique for constructing flexible distributions to facilitate better modeling of lifetime data. In this paper, a new family of lifetime distributions, called the generalized inverse Weibull power ser...

Type II Half Logistic Rayleigh Distribution: Properties and Estimation Based on Censored Samples

Muhammad Ahsan Ul Haq, Abdullah M. Almarashi, Amal S. Hassan & M. Elgarhy · Journal of Advances in Mathematics and Computer Science · 2018

In this paper, we introduce a new model called the Type II half logistic Rayleigh (TIIHLR) with U-shaped, increasing and decreasing hazard rate function. Some structural properties of the current distribution are derived including; explicit expressions for moments, incomplete mom...
