Order statistics arising from exponentiated gamma (EG) distribution are considered. Closed from expressions for the single and double moments of order statistics are derived. Measures of skewness and kurtosis of the probability density function of the rth order statistic for different choices of r, n and /theta are presented. Recurrence relations between single and double moments of r...

In this paper, an attempt is made to discover the distribution of COVID-19 spread in different countries such as; Saudi Arabia, Italy, Argentina and Angola by specifying optimal statistical for analyzing mortality rate COVID-19. A new generalization recently inverted Topp Leone distribution, called Kumaraswamy Topp–Leone proposed combining Kumaraswamy-G family distribution. We initially provide...

A new flexible univariate probability distribution was defined in this paper. The is so called the ‘exponentiated Gumbel–Weibull {logistic} distribution’ and it arose by using exponentiated Gumbel to generate a generalized Weibull logit function or quantile of logistic as link. observed be both unimodal bimodal well exhibits various shape tail properties consistent with data arising from severa...

Exponentiated models have been widely used in modeling various types of data such as survival and insurance claims data. However, the exponentiated composite distribution not explored yet. In this paper, we introduce an improvement one-parameter Inverse Gamma-Pareto model by exponentiating random variable associated with function. The goodness-of-fit was assessed using three different sets. two...
