st: basic question about multi-level data

[Richard Sherman <richard.sherman@mac.com>]

Dear Statalist,

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
