In this paper, a new distribution called the Kumaraswamy-Rani (KR) distribution, as a Special model from the class of Kumaraswamy Generalized (KW-G)
distributions, is introduced. Its statistical properties are explored. Estimation parameters based on maximum likelihood are obtained. We have illustrated the
performances of the proposed distribution by some simulation studies. Finally, the significance of the KR distribution in terms of modeling real data set has been
highlighted before it has been compared to some one parameter lifetime distributions.
