Comparative Analysis of Methods of Estimating 2- Parameter Weibull Distribution

Egwim, Kenneth C., Eke, Charles N., Onuoha, Desmond O, Igbo Celestine A.


This work focused on comparing three methods of estimating 2-parameter Weibull distribution by using the Mean Squared Error (MSE) as test criterion. Three methods of estimation were used, namely, maximum likelihood estimator, method of moments and least squares methods. The method of moments was selected as the best method based on the selection test criterion.

Keywords: Weibull, Moments, Estimators, and Model
