" We have determined that this is caused by a bug in -ivtobit- return
values, which we have worked around and reported to StataCorp."
So the update to -overid- is somewhat ephemeral itself then? Once the
official -ivtobit- has been fixed, -overid- can revert to its state of last
night?

The overid routine of Baum, Schaffer, Stillman and Wiggins (LLP) has been
upgraded to deal with two reported issues. First, the routine failed to run
after -ivtobit-. We have determined that this is caused by a bug in
-ivtobit- return values, which we have worked around and reported to
StataCorp. Second, my code for handling -reg3- models worked fine on Klein's
Model I but gobbled huge chunks of memory on a sizable model. Austin Nichols
kindly provided a more economical routine, which is now installed in overid.
It should now be fully compatible with Stata 11.
overid might be useful for those still working with Stata 9.2, as it can be
used after official -ivreg- (or Baum-Schaffer-Stillman -ivreg2-) to produce
overidentification tests. For more recent versions, -estat overid- may be
used after -ivregress-.
To install, use ssc inst overid, replace or adoupdate.
