Natasha Sarkisian <[email protected]> noticed the absence of the -svy-
option in the Stata 9 -suest- command:

Natasha makes an important point. Currently, -suest- requires -svy-
estimation results, but -zip- and -zinb- do not support the -svy- prefix. We
will bring back the -svy- option to -suest- to accommodate estimation commands
that do not support the -svy- prefix. We hope to have the update to -suest-
available in the next ado-file update.
