Nick is correct, -zoib- was not written for panel data. In the help
file you can see that weights, clustered, and/or robust standard
errors are allowed, but not the -svy- prefix, which is required for
strata. In general a help-file lists wat is allowed, thus anything
that is not listed in the help-file is not allowed. So that is how you
could have used the helpfile to answer your question on -zoib- and
panel data.
