The UNIVARIATE procedure provides the following:
descriptive statistics based on moments (including skewness and kurtosis), quantiles or percentiles (such as the median), frequency tables, and extreme values
histograms that optionally can be fitted with probability density curves for various distributions and with kernel density estimates
cumulative distribution function plots (cdf plots). Optionally, these can be superimposed with probability distribution curves for various distributions.
quantile-quantile plots (Q-Q plots), probability plots, and probability-probability plots (P-P plots). These plots facilitate the comparison of a data distribution with various theoretical distributions.
goodness-of-fit tests for a variety of distributions including the normal
the ability to inset summary statistics on plots
the ability to analyze data sets with a frequency variable
the ability to create output data sets containing summary statistics, histogram intervals, and parameters of fitted curves
You can use the PROC UNIVARIATE statement, together with the VAR statement, to compute summary statistics. See the section Getting Started: UNIVARIATE Procedure for introductory examples. In addition, you can use the following statements to request plots:
the CDFPLOT statement for creating cdf plots
the HISTOGRAM statement for creating histograms
the PPPLOT statement for creating P-P plots
the PROBPLOT statement for creating probability plots
the QQPLOT statement for creating Q-Q plots
the CLASS statement together with any of these plot statements for creating comparative plots
the INSET statement with any of the plot statements for enhancing the plot with an inset table of summary statistics
The UNIVARIATE procedure produces two kinds of graphical output:
ODS Statistical Graphics output, which is produced when ODS Graphics is enabled prior to your procedure statements
traditional graphics, which are produced when ODS Graphics is not enabled
See the section Creating High-Resolution Graphics for more information about producing traditional graphics and ODS Graphics output.
