<> Try ************* ssc d overid ************* where no promise is made of any support for -ivregress-. HTH Martin -----Ursprüngliche Nachricht----- Von: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] Im Auftrag von xueliansharon Gesendet: Donnerstag, 15. Juli 2010 17:20 An: statalist@hsphsun2.harvard.edu Betreff: st: overid after ivregress Dear all, I meet a strange problem, the command "overid" can't be used after ivregress, the error message is "overid not supported for command ivregress last estimates not found r(301)" This is strange, since in the help file of overid, it says that overid can "Calculate tests of overidentifying restrictions after ivregress, ivreg2, ivprobit, ivtobit, and reg3", so why does this problem happen? BTW, my version for overid is st0030_3 . The commands I use are: sysuse auto ivregress 2sls price mpg (weight turn=length displacement gear_ratio trunk) overid Hope to get your help.
