PROC MIXED By statement

tbanh — Fri, 04 Mar 2016 23:32:41 GMT

Hi all,

I have a dataset below and I wanted to fit a mixed model using PROC MIXED. I have a BY variable named Size, which indicates the sample size. I was wondering if there was any way I could limit the analyses to just Size = 5. So something like:

PROC MIXED data = SimulatedData;
by Size = 5;
model...;
random...;
repeated...;
run;

but the BY statement will not allow me to specify a certain condition for the variable. Does anybody have any ideas?

Try

WHERE size=5;

In the BY statement?

If you only have one size the BY doesn't matter - you only have one set of results.

The WHERE is its own statement.

You our can leave the BY in, if your using it to generate titles.

To be clear, use:

proc mixed data=simulateddata(where=(size=5));
