DUS-Kumaraswamy Distribution: A Bathtub Shaped Failure Rate Model
K.K. Anakha , V. M. Chacko
Abstract
In this paper, we study a statistical distribution using DUS transformation with Kumaraswamy distribution as the baseline distribution. The distribution has increasing as well as bathtub behavior for the failure rate function. Various statistical properties including moments, moment generating function, characteristic function, quantiles and entropy are discussed. Maximum likelihood estimation method is given for the estimation of parameters. Reliability estimation of the stress-strength model is described. A simulation study is conducted to validate the model. Real data set is used to illustrate the findings.
