You use the empty model to predict the interclass correlation. Is this the correct SAS model to do that? I am not sure if you specify the intercept as random or not.

proc mixed data= work.test4 covtest noclprint;

class unitid_pri ;

model weeklyearnings_clo = /solution;

random intercept /subject= unitid_pri;

run;

While I am at it the link below has a macro that performs the LR deviance test with mixed p values (both strongly recommended especially with random effects). One thing that is unclear to me is if you have to run the

%include '\\cdc\private\mixture method pvalue macro1.sas'; macro always or whether this unique to the data the author is using. He never mentions this macro at all.
