Abstract

In this paper, we use the moment of order statistics for testing mixture of two Weibull distrimutions (MTWD) by using correlation-type goodness-of fit test. Also, we show the performance of the test by calculating the power based on some alternative distributions including; normal, gamma, lognormal, Weibull and the mixture of gamma and lognormal distributions. In addition, we discuss a numerical example. Finally, we apply our results to real lifetime data.
