Are Histograms Giving You Fits? New SAS Software for Analyzing Distributions

Abstract

Exploring and modeling the distribution of a data sample is a key step in many applications of statistics and data mining. This presentation will introduce you to software for creating high-resolution graphics displays of data distributions, including histograms, probability plots, and quantile-quantile plots, which have been added to the UNIVARIATE procedure in Version 8. Comparative versions of these displays are available, along with statistical methods for fitting parametric and nonparametric distributional models. For data involving multiple samples, you can create box plot displays with the new BOXPLOT procedure in SAS/STAT software.
