The influence of threshold stress on the estimation of the Weibull statistics is discussed in terms of the Akaike information criterion. Numerical simulations show that, if sample data are limited in number and threshold stress is not too large, the two‐parameter Weibull distribution is still a preferred choice. For example, the fit of strength data of glass and ceramics to the two‐ and three‐parameter Weibull distributions is compared.
