In this article, we introduce a new class of five-parameter model called the Exponentiated Weibull Lomax arising from generated family. The contains some existing distributions as well models. Explicit expressions for its moments, distribution and density functions, moments residual life function are derived. Furthermore, Rényi q–entropies, probability weighted order statistics obtained. Three ...

The so-called Kumaraswamy distribution is a special probability developed to model doubled bounded random processes for which the mode do not necessarily have be within bounds. In this article, generalization of called T-Kumaraswamy family defined using T-R {Y} distributions framework. resulting obtained quantile functions some standardized distributions. Some general mathematical properties ne...

Problem Statement: The two-parameter exponentiated Rayleigh distribution has been widely used especially in the modelling of life time event data. It provides a statistical model which has a wide variety of application in many areas and the main advantage is its ability in the context of life time event among other distributions. The uniformly minimum variance unbiased and maximum likelihood es...

in this paper, we study the estimation problems for the two-parameter exponentiated gumbel distribution based on lower record values. an exact confidence interval and an exact joint confidence region for the parameters are constructed. a simulation study is conducted to study the performance of the proposed confidence interval and region. finally, a numerical example with real data set is given...

In this paper, a new three-parameter extension of the generalized geometric distribution of [6] is introduced. The new discrete distribution belongs to the resilience parameter family and handles a decreasing, increasing, upside-down and bathtub-shaped hazard rate function. The new distributions can also be considered as discrete analogs of some recent continuous distributions belonging to the ...
