초 록
The Weibull variate is commonly used as a lifetime distribution in reliability applications. Estimation of parameters is revisited in the twoparameter Weibull distribution. The method of product spacings, the method of quantile estimates and the method of least squares are applied to this distribution. A comparative study between a simple minded estimate, the maximum likelihood estimate, the product spacings estimate, the quantile estimate, the least squares estimate, and the adjusted least squares estimate is presented.
