When estimating the parameters of the Weibull distribution, the general assumption is that the experimental data used in the estimation procedure is uncontaminated. Under this assumption, there are no outliers in the data resulting from either erroneously recorded measurements or unusual operating conditions, etc. However, it’s important to note that the no-contamination assumption may not hold in practice. If this assumption is seriously violated, the parameter estimates of the Weibull distribution can be significantly affected by the contaminated data. Therefore, a robust approach to Weibull estimation is clearly warranted. In this article, we describe various methodologies that can be used to estimate the parameters of the Weibull distribution. We then conduct a study using both real data and simulated data to compare the robustness properties of these methods. The study provides strong evidence that the robust regression line fitted to the Weibull plot is the most robust among the various Weibull parameter estimation methodologies considered here.
