Log Linear Variance Model

bayoote — Wed, 12 Feb 2020 23:34:07 GMT

Hi All,

I want to build a log linear variance model and test the slices for the interaction term. I know I can use the proc genmod procedure. However, it only gives me the plot of slices test. I am thinking that whether I can use proc mixed procedure to build the log linear model? anyone knows how to do that? Thanks!

If you show the code you are currently using you may get suggestions on where to modify it.

Simple: copy the program text from your SAS editor then open a code box on the forum using either the {I} or the "running man" icon and paste the code.

The code boxes help prevent the forum windows from stripping out white space like code indents and such to preserve readability.

I don't know Log linear variance model.

But I know PROC CATMOD can do Log Linear Model .

But for PROC MIXED , You could try Possion distribution and LOG linked function .
