SAS supports more than 25 common probability distributions for the PDF, CDF, QUANTILE, and RAND functions. If you need a less-common distribution, you can implement new distributions by using Base SAS (specifically, PROC FCMP) or the SAS/IML language. On the SAS Support Communities, a SAS programmer asked how to implement the generalized extreme value (GEV) distribution in SAS. This article shows how to use PROC FCMP and PROC IML to implement functions for working with the GEV distribution. T...| The DO Loop

While researching a topic on effect sizes, I learned about a SAS function that is related to noncentrality parameters. I previously wrote an article about the noncentral t distribution, which is one of several well-known distributions that contains an optional noncentrality parameter. I mentioned that the PDF, CDF, and QUANTILE functions in SAS support an optional noncentrality parameter for the t, chi-square, and F distributions. However, I did not know until recently that SAS also provides ...| The DO Loop
