Hi,
I'm trying to do a Hausman test for checking endogeneity. I have cross sectional data with a matched pair design.
I'm using clogit for regression.
In understand that hausman test can be used as a post estimation test to check for endogeneity in STATA.
I have used the following commands, however hausman test requires two models to be specified. One before allccats and one after allcats.
a) clogit FFVsCF l_DirectorsTotalCompensation RoE RoA MVBV AvgAge BoardSize IndDirPRCT FeDirPRCT ExecDirPRCT CDual MLEV ABig4 NoBM, group(MatchID)
b) estimates store allcats
c)
d) hausman . allcats, alleqs constant
My question is which model to specify in the second round (refer to point (c) above).
Can anyone please guide me.
Best regards, Juhee
