Distribution Analysis: Distributional Modeling
You can use the Distributional Modeling analysis to fit parametric distributions to univariate data. You can estimate parameters for the fitted distributions, compute goodness-of-fit statistics, and display quantiles of the fitted distributions.
You can use this analysis to create a histogram overlaid with up to five density curves. You can create a quantile-quantile (Q-Q) plot to help you determine how well a given distribution fits the data. You can also create a plot of the empirical cumulative distribution function.
You can run a Distributional Modeling analysis by selecting Analysis 
Distribution Analysis Distributional Modeling from the main menu. When you request distributional modeling, SAS/IML Studio calls the UNIVARIATE procedure in Base SAS. See the UNIVARIATE procedure documentation in the Base SAS Procedures Guide for additional details.
