| Abstract: | The percentile estimate,inverse moment estimate, and modified maximum likelihood estimate of the three-patameter Weibull distribution are presented. Then, with the help of Monte-Carlo simulation in senses of bias and mean square error, the advantages of the three estimates and simple estimate are studied. Finally, based on the optimization point estimates of the three parameters, the Bootstrap confidence bounds of the reliability R(t) are provided, |
