One more question:

So how do I do that: I have a dataset with, let's say, 10 countries,
and I would like to impute values for only 3 countries because in
these, many gross wages are missing. Is there an option in -ice- like:
if country==2? Or should I separate the 3 countries from the file, use
ice, and then append all 3 again to the main dataset? It is probably
easier to impute all missings (there are a few in the other countries
aswell) of the gross income, so I would include country as an
explanatory variable - but I think this would be less exact as doing
it for each country separately.

I am also not sure which dataset to use after -ice-. Let's say I
specify the option m(5) of -ice- for generating 5 datasets, do I in
the end use number 5 for my estimations? If I do ice for the 3
countries separately, I cannot append all, because the variables that
are created in the ice proecedure will not be the same in all
datasets, right?
