In this paper a new four-parameter lifetime distribution named “the Exponentiated gompertz-poisson (E-GP) distribution” has been suggested that it has a decreasing, increasing, bathtub-shaped and inverse bathtub-shape for modeling lifetime data. The Exponentiated gompertz-poisson has applications in economics, actuarial modelling,reliability modeling, lifetime and queuing problems and biologica...

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 ...
