st: Question on xthtaylor

["Roy,Suryadipta" <suryadipta.roy@lawrence.edu>]

Hi,

There have been a few threads on the first one, but I am 
still asking the question to find out if there is an 
easier solution:

1. Is there a command to obtain robust/ cluster(robust) 
standard errors while using xthtaylor (as in xtreg, fe or 
xtreg, re)?

2. Is there a command to obtain R-square while using 
xthtaylor?

3. Moreover, after I run xthtaylor, I am trying to do the 
overidentifiaction test with -xtoverid- but I am getting 
an error message : "invalid name". I only have 
time-varying variables as endogenous variables.

Any comment on these issues would be really helpful.
Thanks as usual!
Suryadipta.
