Betreff: st: problems with ivreg2 and xtivreg2
Dear Stata List members
I have upgraded online my version of stata from stata8 to stata8.2
I am interested in two commands:
ivreg2 and xtivreg2
when I run ivreg2 stata says
unrecognized command: mata
(error occurred while loading ivreg2.ado)
r(199)
and no output is returned
when I run xtivreg2 stata says
unrecognized command: mata
but then the output follows
what does this mean and how could I overcome these problems?
thank you in advance for any help
sara
