In this paper, a new modified Kumaraswamy distribution is proposed, and some of its basic properties are presented, such as the mathematical expressions for moments, probability weighted order statistics, quantile function, reliability, entropy measures. The parameter estimation done via maximum likelihood method. to show usefulness proposed model, well-established actuarial measures value-at-r...

The Kumaraswamy distribution is an important probability used to model several hydrological problems as well various natural phenomena whose process values are bounded on both sides. In this paper, we introduce a new family of inverse and then explore its statistical properties. Conventional maximum likelihood estimators considered for the parameters estimation based dual generalized order stat...

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...
