The following SAS/IML program simulates 5,000 samples of size n and computes the maximum value of each sample. Extreme value theory or extreme value analysis (EVA) is a branch of statistics dealing with the extreme deviations from the median of probability distributions.It seeks to assess, from a given ordered sample of a given random variable, the probability of events that are more extreme than any previously observed.
