Abstract

Weibull distribution is commonly applied in survival analysis and reliability analysis, whose shape and scale parameters are most commonly estimated by maximum likelihood estimation and related numerical methods. In this paper, by introducing an artificial parameter and then using the perturbative method, for the first time in the statistics literature, we conveniently obtain approximate analytical formulas of maximum likelihood estimates of the parameters in Weibull distributions, which are important complements to those tedious and unreliable numerical methods. Monte-Carlo simulations show that the approximate analytical method proposed in this paper is fairly feasible and accurate. Using the similar method, we can also obtain the approximate analytical formulas of maximum likelihood estimates in many other statistical problems.
