摘要
A new class of distributions containing Marshall-Olkin extended Weibull distribution is introduced. The role of this distribution in the study of minification process is established. A new class of distributions that includes the Laplace and Logistic distributions is introduced. Properties and generation of Marshall-Olkin extended Double Weibull distribution and Marshall-Olkin extended asymmetric double Weibull distribution are discussed. The distribution of daily stock price index of Bombay stock exchange (INDIA) is identified as generalised asymmetric double Weibull model and its estimation and predictions are done.
