Improving the 1-Parameter Weibull: A Bayesian Approach

by Aron, Alexander; Guo, Huairui; Mettas, Adamantios; Ogden, Doug

In this paper, a Bayesian model, which is an improved approach for the 1-parameter Weibull, is discussed. Recommendations for establishing variability models for the Weibull shape parameter are presented..
