SAS programs

All of the graphs shown here were constructed with SAS/GRAPH software. Most of the SAS programs are available on SAS for Windows on the Hebb server for the Psych Lab, and on phoenix.yorku.ca. You may also access some of these via the World Wide Web at

http://www.math.yorku.ca/SCS/friendly.html

Some of these are designed as general macro programs which can be used with any set of data; others are specific to the particular application.

The following programs are currently available:

CATPLOT: [Macro] Plot predicted logits from CATMOD
CATDEMO: Demonstration of CATPLOT
FOURFOLD: IML modules for four-fold display of 2 x 2 x k tables
FOURDEMO: Demonstration of FOURFOLD
GLOGIST1: Logistic regression: binary response
GLOGIST2: Logistic regression: proportional odds model
INFLOGIS: [Macro] Influence plots for logistic regression
KAPPA: Calculate Cohen's kappa for agreement
LABEL: [Macro] Label points on a plot
MOSAICS: IML modules for mosaic displays
MOSADEMO: Sample program for mosaic displays
POISPLOT: [Macro] Poissonness plot
POISDEMO: Demonstration of Poissonness plot
ORDPLOT: [Macro] Ord plots for discrete distributions
ORDDEMO: Demonstration of Ord plot
SIEVE: IML modules for sieve diagram
SIEVDEMO: Demonstration for sieve diagram

The SAS programs from Agresti's An Introduction to Categorical Data Analysis are also on the Web.

Other methods for graphical display of data are described in my book, SAS System for Statistical Graphics, First Edition
