Evaluating Weibull Endurance Data by the Method of Maximum Likelihood

Abstract

The method of maximum likelihood has been found to offer many advantages over existing methods for analyzing Weibull distributed rolling bearing fatigue data.

The purpose of this paper is to provide the rolling bearing engineer with what he needs to use the method of maximum likelihood for, 1) Unbiased estimation of Weibull L₁₀ life and shape parameter. 2) Setting confidence limits and testing hypotheses about Weibull L₁₀ life and shape parameter. 3) Unbiased estimation of the ratio of two population L₁₀'s and shape parameters. 4) Testing the significance of differences between two estimates of L₁₀ life or shape parameter.
