Does anyone know how to test for a fixed effect and clustering in your data on SAS?
I know this process is quite simple on stata just a matter of dropping an ", fe" and ", vce(cluster permno)" at the end of the OLS regression command.
I am hoping SAS has an equally similar edit to the following command:
proc reg data = have;
model income = size price earnings sales expenses ROA ATO;
Or am I wishful thinking? Help on how to test for this would be greatly, appreciated.
