An efficient two-step method of estimating the scale parameter of the Weibull distribution is presented and compared to other estimation procedures. The shape parameter is obtained by a procedure other than maximum likelihood and then substituted into the maximum likelihood formula for the scale par

Newton-Raphson's method plays a fundamental role in the maximum likelihood estimation of the two parameters of the Weibull probability distribution. It is well known that the method depends on the initial point of the iterative process and the iteration does not always converge. In the present art
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
