SAS macro programs

The SAS macro programs described here are available for use on the Phoenix system under unix and on SAS for Windows on the PAVLOV server for the Psych Lab.

To make them automatically available on Phoenix, type the command,

setenv SAS_OPTIONS "-autoexec /courses/as/psyc/autoexec.sas"

If you add this line to your .cshrc file, this will be setup each time you login. This step is unnecessary on PAVLOV Then to use one (say, BOXPLOT) in your SAS program, simply call the macro as, for example,

%boxplot(data=nations, var=imr, class=region);

Programs

The following programs are currently available:

BIPLOT: Biplot technique
BOXANNO: Marginal boxplot annotations for scatterplots
BOXCOX: Box-Cox transformations for regression models
BOXGLM: Box-Cox transformations for GLMs
BOXPLOT: Boxplots and notched boxplots
CONTOUR: Elliptical contours for scatterplots
DOTPLOT: Dot charts
INFLPLOT: Influence plots for regression models
LOWESS: Lowess scatterplot smoothing
NQPLOT: Normal Q-Q plots
OUTLIER: Multivariate outlier detection
PARTIAL: Partial regression residual plots
RESLINE: Resistant lines by 3-point method, with transformations
SCATMAT: Scatterplot matrices
STARS: Star plots
SYMPLOT: Symmetry transformation plots

These and other methods for graphical display of data are described in my book, SAS System for Statistical Graphics, First Edition available from SAS Institute.
