In this work, we propose and study a new discrete analogue of the Weibull class. Many
useful properties such as ordinary moments; moment generating function; cumulant …

A new modified version of the Bagdonavičius and Nikulin goodness-of-fit statistical test is
presented and investigated for validity under the exponentiated Rayleigh generalized Chen …

After defining a new log-logistic model and studying its properties, some new bivariate type
versions using “Farlie-Gumbel-Morgenstern Copula”,“modified Farlie-Gumbel-Morgenstern …

In this paper we present a new G family of probability distributions. Some of its mathematical
properties are derived. Based on a special member of the new family, a single acceptance …

This paper introduces a new extension of the Gompertz function for estimating the survival
rates. The actual survival rates from USA life tables 2015 is considered for assessment …

We introduce a new continuous distribution based on the zero truncated Poisson model
which accommodates many important failure rate shapes. Some of its mathematical …

A new generalization of Lomax distribution is derived and studied. Some of its useful
properties are derived. A simple clayton copula is used to generate many bivariate and …

The future values of the expected claims are very important for the insurance companies for
avoiding the big losses under uncertainty which may be produced from future claims. In this …

This paper presents a novel two-parameter G family of distributions. Relevant statistical
properties such as the ordinary moments, incomplete moments and moment generating …

A new two-parameter lifetime distribution is proposed and numerically studied. The new
model has a flflexible failure rate shapes such as “monotonically increasing”,“monotonically …
