Put strata dummies into every equation. Note that by using the
imputation model that uses information across strata, you lose the
great advantage of stratified samples, namely, that the estimates
based on different strata are independent. Hence, the -strata()-
option of -svyset- is no longer appropriate.
My understanding is that the interplay of multiple imputation and
thorough design-based survey statistics is still underdeveloped. I am
trying to keep an eye on both, but haven't seen anything decent since
Shao & Sitter (1996,
