Dear all:
I am trying to obtain the standard deviation of the
error from a tobit model. I tried the fitstat utility
in v. 9 and got the message "variable _se not found".
Going through some earlier posts, I thought the
problem was with version 9 in particular, so I changed
my version to 8 - but the problem remains.
I've tried "predict stdr" but this will not work
either.
I'd be grateful for any advice on how to derive the
standard error for a tobit model.
Many thanks in advance.
Emma
Make sure you have the most current version of fitstat. It is not the version that is at SSC. Rather, it is on J. Scott Long's personal site and is part of his -spost9- package. Type

findit spost9

to locate it. If problems persist, let us know.
