A student of mine is working with a type of data with which I have no
experience. The key feature of the data is that the unit of
observation/analysis is multi-level, with some observations measured
at the level of specific neighborhoods, others at a region larger
than a neighborhood, and some at the whole city (in this case
Baghdad). That is, the same variables are measured over different units.
Ordinarily when I get close to this type of data, I start moving in
the other direction without delay. But I know vaguely of the
existence of multi-level techniques, and I thought I'd ask you all
for where in Stata I should be looking to start finding out about how
and whether to do this type of analysis. Thanks for your help,
Richard
