SpletThe Weibull distribution (usually sufficient in reliability engineering) is a special case of the three parameter exponentiated Weibull distribution where the additional exponent equals 1. The exponentiated Weibull distribution accommodates unimodal, bathtub shaped and monotone failure rates. SpletThe Weibull distribution includes the exponential (β =1) and the Rayleigh distribution (β =2) as special cases. If X denotes the Weibull vari-able, then −X has a type 3 extreme-value dis-tribution [3.8, Chapt. 22].
