The Kumaraswamy distribution is a common type of bounded distribution, which widely used in agriculture, hydrology, and other fields. In this paper, we use the methods likelihood ratio test, modified information criterion, Schwarz criterion to analyze change point distribution. Simulation experiments give performance three methods. application section illustrates feasibility proposed method by ...

In this paper, the log-exponentiated Kumaraswamy (LEK) distribution is introduced and studied as a survival model of unemployment, its survived function has the interesting property that it can be decreasing depending on the shape parameters. The method of maximum likelihood is applied for estimating the model parameters, survival and hazard rate functions. Stratification is used to reduce hete...
