摘要：A mixture of Weibull distribution, involving two shape parameters, two scale parameters, and one proportionality parameter, is simulated through the statistical software MINITAB (1996). The two methods Graphical (John H.K. Kao 1959) and moments based (Lee W. Fall 1970) are applied to estimate the underlying five parameters of mixed Weibull distribution in order to find the accuracy and precision of the estimator.
