Re: st: Grouping income variables- RECODE COMMAND

[Maarten Buis <maartenlbuis@gmail.com>]

Multiple imputation is in principle very easy, but in practice getting
the right imputation model is a very finicky process. So this is
something where I do not feel comfortable giving you advise without
seeing the data and discussing in detail (face to face) what your
analysis plan is. Your best chance is to find a local expert and meet
her or him (and be prepared to pay, because you will be asking a lot
from her or him).
