A consideration on estimation of the Weibull parameters

Abstract (in Japanese) (See Japanese page) 
(in English) Two methods for parameter estimation of the three-parameter Weibull distribution are proposed. In the both methods, the estimate of the shape parameter can be optained by minimizing a function of only one parameter and the estimates of the location and scale parameters can be obtained by two closed-formed formulas. A simulation study shows that the proposed estimators are generally better than the modified moment estimators and the modified maximum likelihood estimators with respect to bias and RMSE.
