In this study, we propose a new three-parameter lifetime model based on the type-I half-logistic G family and unit-Gompertz model, which named unit Gompertz distribution. The key feature of such novel is that it adds tuning parameter to using in order make more flexible. Diagrams numerical results are used look at model’s mathematical statistical aspects. efficiency estimating distribution para...

In this article, four new families named as Weibull extended exponentiated-X (WEE-X), Lomax (LEE-X), Logistic (LGCEE-X), and Burr III (BIIIEE-X) with their quantile functions are proposed. The expressions for distribution function density of BIIIEE-X family written in terms linear combinations the exponentiated densities based to parent model. New models, i.e., Weibul (WEEW), (LEEW), (LGCEEW), ...

This article proposes a new distribution call the Exponentiated Power Lindley-Logarithmic Distribution for modeling real life data. The is motivated by Lindley distribution. quantile function derived and Maximum likelihood estimates of parameters are also derived. performed better in simulation study than competing can model biomedical phenomena agricultural events.

In this paper, we introduce a new four-parameter generalized version of the Chen model called exponentiated extended distribution. Some results about reliability characteristics hazard rate function as well some mathematical properties are provided. The maximum likelihood estimators and five approaches based on concept minimum spacing distance given for estimation parameters their performances ...
