Dear statalisters:
In stata help pages vce(cluster, clustervariable) and vce (bootstrap)
has been mentioned as options but when I try to run it says
ivprobit dependent x y l.z (zz = mz pz), vce(cluster, country),
twostep, first
invalid 'twostep'
r(198);
. ivprobit dependent x y l.z (zz = mz pz), vce(cluster, country), first
invalid 'first'
r(198);
. ivprobit dependent x y l.z (zz = mz pz), vce(cluster, country)
option country not allowed
r(198);
. ivprobit dependent x y l.z (zz = mz pz), vce(boot)
time-series operators are not allowed with bootstrap without panels, see
tsset
r(198);
Only option it accepts is vce(robust). While I want to bootstrap
standard errors on clusters. I understand that ivprobit is not for panel
then why this option has been given after ivprobit. can anybody help?
best regards,
Shehzad
