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, Stat Studio
calls the UNIVARIATE procedure in Base SAS.
See the UNIVARIATE procedure documentation in the
Base SAS Procedures Guide for
additional details.
