β¦ Synopsis
Maximum likelihood estimation for the parameters in the three-parameter Weibull distribution needs an initial value in the iteration scheme for likelihood equations. In certain cases, maximum likelihood estimation can break down for the three-parameter Weibull model, as no local maximum of the likelihood exists. To avoid these difficulties, we suggest a modification of the weighted least-squares estimators for the three-parameter Weibull distribution. The modification presented here is to find an estimate for a threshold parameter for this distribution.

This paper is concerned with the parameter estimation problem for the three-parameter Weibull density which is widely employed as a model in reliability and lifetime studies. Our approach is a combination of nonparametric and parametric methods. The basic idea is to start with an initial nonparametr
This paper discusses exact joint confidence region for the shape parameter /J and scale parameter I1 of the two-parameter Weibull distribution. As an application, the joint conlidence region is used to obtain a conservative lower confidence bound for the reliability function. The method can be used
