For example, we can test homogeneity of variance with PROC GLM.
The procedure calculates residuals as we can see it in the formula for Levene’s HOV test.
Is this implicit residual calculation common situation for SAS procedures or not ?
Can we save the residuals computed by a PROC into a table ?
Thank you.
SAS regression procedures enable you to output residuals (and standardized residuals, and predicted values, and confidence limits, and...) by using the OUTPUT statement. Different procedures support different keywords, as applicable.
To get the residuals in PROC GLM, add this line to your procedure call:
output out=MyOutput R=Residuals;
That will create an output data set calls "MyOutpuit" which contains the input data and a new column called "Residuals" that contains he residual value for each observation.
