I believe that ivendog assumes conditional homoscedasticity and cannot be
used with either the cluster or robust options.

See "ivendog", this test for the endogeniety after ivreg and ivreg2.
running ivendog after ivreg2 you'll get Wu-Hausman F test and
Durbin-Wu-Hausman chi-sq test.

for example:
* do file starts here----------------------------
ivreg2 y1 (y2 = x4 x5) x1 x2 x3 , gmm robust cluster(subjid)
* do file end here ---------------------------

I hope this helps.
