    Hi All,
    We are told that you should not use Weibul to transform tensile data (left skew).
    Is this a golden rule or can it be flexible????

    Pat,
    The logic use of the Weibull distribution to model a data set is like the use of any other distribution in that it depends on the overall data characteristics and the fit.  No golden rule here….  
    If you have Minitab14 use Stat<Quality Tools<Individual Distribution Identification and look for the best fit (lowest AD)..  If it's Weibull, go with it….
    Best Regards,
    Bob J
