We are trying to fit some "long tail" distributions, either generalized extreme value distributions, power laws, etc. But we have little experience with it and wondered if anyone else had used SAS to do something similar. Thanks for any feedback.
PROC CAPABILITY can fit a wide variety of distributions, including the Johnson family of distributions, which would allow you to fit very long tailed distributions.
ANOVA, or Analysis Of Variance, is used to compare the averages or means of two or more populations to better understand how they differ. Watch this tutorial for more.
