A new generalization of the exponential distribution, namely generalized mixture is introduced. Some its basic properties, such as hazard function, moments, order statistics, mean deviation, measures uncertainly, and reliability probability, are studied. Three different estimation methods investigated by maximum likelihood estimator, least-square weighted estimator. The performances estimators ...

A five-parameter distribution called Beta Generalized Weibull (BGW) distribution is introduced. Beta Generalized Exponential (BGE), Beta Weibull (BW), Generalized or Exponentiated Weibull (GW or EW), Generalized Rayleigh (GR), Beta Exponential (BE), Generalized Exponential (GE), Weibull, Rayleigh and Exponential are its sub models. The cumulative distribution function (cdf) and the probability ...

A three parameter continuous probability distribution Modified Inverse Generalized Exponential Distribution: Model and Properties, is introduced in this article. To study the properties of model, distribution, density, survival hazard rate functions are introduced. data real life used for checking application. Some important methods estimation constants. validation checked using Akakie’s inform...
