(Adapted from http://www.yorku.ca/dept/psych/lab/sas/sasanova.htm, by Michael Friendly, York University, Ontario, Canada.)
This is meant to be a brief summary of
the syntax of the most widely used statements with PROC ANOVA
There are actually more statements and options that can be used
with proc ANOVA -- you can find out by typing HELP ANOVA
in the command area on the main SAS Display Manager Window. For
further information, you might look at Linear Models in SAS An overview of regression and analysis of
variance procedures. (from Univ. Michigan).
In the statements below, uppercase is used for keywords, lowercase for things you fill in. Variable names are no more than 8 chars. in length.
PROC ANOVA handles only balanced ANOVA designs.
PROC ANOVA DATA=datasetname;
CLASS factorvars;
MODEL responsevar = factorvars; /* See below */
MEANS factorvars / BON /* Bonferroni t-tests,
g=r(r-1)/2 */
T or LSD /* Unprotected t-tests */
TUKEY /* Tukey studentized range */
SCHEFFE /* Scheffe contrasts */
ALPHA=pvalue /* default: 5% */
CLDIFF /* Confidence limits */
LINES /* Non-significant subsets */
; /* use LINES or CLDIFF */
