Does it depend on the version of STATA? Someone mentioned about it but I am
not sure.

I list again 'cause no one answer.
What am I supposed to do for this error?
xi: xtivreg2 y (x1 x2 x3 = iv1 iv2 iv3 iv4 iv5) i.time, fe small
cluster(group)
i.time _Itime_1-50 (naturally coded; _Itime_50 omitted)
Warning - singleton groups detected. 1 observation(s) not used.
panelsetup_u(): 3301 subscript invalid
panelsetup(): - function returned error
rkstat(): - function returned error
<istmt>: - function returned error
I followed the prevous directions. But Still.
My stata is version 10 with 64-bit
Which versions of -xtivreg2-, -ivreg2- and -ranktest- are you using?
And have you updated your version of Stata with -update all-?
In my experience these Mata errors usually go away after a full
updating.
--Mark
Just in case, I experimented why it has the errors.
xi: xtivreg2 y (x1 x2 x3 = iv1 iv2 iv3 iv4 iv5) i.time, fe
small --> no
errors
xi: xtivreg2 y x1^ x2^ x3^ i.time, fe small cluster(group)
--> no errors
where X1^ indicates the instrumented value of x1 in the first stage.
I hope these experiments to help you to answer me.
