GLM residual plots?

mhlinder — Mon, 02 Feb 2015 23:52:54 GMT

This is a very basic question, but I am new to SAS and cannot find any resources related to the problem I am having.

I am running an ANOVA using the GLM proc, and would like to produce a plot of the residuals. I have attempted to do so with the following:

PROC GLM DATA=indata PLOTS=RESIDUALS;

CLASS Treatment;

MODEL Response = Treatment;

RUN;

The ANOVA table is produced as desired, but the corresponding residuals plot is not...can anyone help me figure out how to get a residuals plot?

I am using SAS 9.4.

Thanks very much!

Best,

Henry

Well, I am still unsure of why this does not work; however, I have found an acceptable solution:

PROC GLM DATA=indata PLOTS(UNPACK)=DIAGNOSTICS;

produces each of the diagnostic plots individually, including a residual plot and a normal probability plot for the residuals.
