Subject   st: random effect analysis on case-control data
Date   Tue, 12 Apr 2005 10:24:27 +0200

I have a case-control dataset with 530 observations, of which 137 cases and 
393 controls. The observations are at the level of the households, but 
households are grouped in villages (15), so I am interested in running a 
random effect model, with a two-level specification. Specifically, I am 
interseted in a random effect logit model since my outcome is binary.

Is the xtlogit procedure adequate to estimate my model, given the case-control 
nature of the data? Are 15 villages enough to estimate level-2 variance in a 
model that uses Gauss-Hermite quadrature?

Thanks in advance for the suport.
