In this paper, we consider a form of the generalized logistic distribution named symmetric extended generalized logistic distribution or extended type III generalized logistic distribution. The distribution is derived by compounding a two-parameter generalized Gumbel distribution with a two-parameter generalized gamma distribution. The cumulative distribution and some properties of this distrib...

In this paper, a four parameters extension of the generalized Lindley distribution is introduced. The new distribution includes the power Lindley, Lindley, generalized (Stacy) gamma, gamma, Weibull, Rayleigh, exponential and half-normal distribution. Several statistical properties of the distribution are explored. Then, a bivariate version of the proposed distribution is derived. Using a simula...

introduction: this paper used generalized gamma (gg) distribution to find the predictive factors of overall survival (os) after haematopoietic stem cell transplant (hsct) in acute myeloid  leukemia patients. methods: discrimination among the exponential, weibull, gg, log-logistic, and lognormal distributions was done using maximum likelihood and akaike information criteria. results: the 5-year ...

in this paper, we consider admissible estimation of the parameter ?r in the gamma distribution with truncated parameter space under entropy loss function. we obtain the classes of admissible estimators. the result can be applied to estimation of parameters in the normal, lognormal, pareto, generalized gamma, generalized laplace and other distributions.

In this paper, after stating the characteristicof some of continuous distributions including, gamma, Crovelli’s gamma, Rayleigh, Weibull, Pareto, exponential and generalized gamma distribution with each other,these distributions were fit on drought data of Guilan state and the best distribution was presented. Then, severity and duration of the drought of different sites were investigated usi...
