Stas,
Thank you so much for the suggestion. That was an easy approach to solving my problem, and even as a newcomer to Stata, I was able to do this.

The data are from a stratified random sample survey. The apc_ie command does not accept the svy prefix in order to accurately estimate variance. Does anyone know of a possible workaround to be able to use this command with survey data?
As far as I understand, the -apc- commands are wrappers around -glm- commands with some equality constraints. The easiest way might be to "unwrap" them and run the bare -svy : glm- with the necessary constraints.
