st: Difference between svy:logit and xtgee - cluster effects.

[jb449755@socsci.aau.dk]

Dear listers,

I'm working with a dataset containing individuals and areas.
Rather than using a multilevel approach to explore the clustereffects  
I'm trying just to take account of the correlation within these  
clusters (areas) in my estimation.

Can anyone please help me to understand the difference between  
svy:logit and xtgee in terms of interpretation of the estimates  
obtained by the different models?
As far as I understand it both models are supposed to 'average out'  
the cluster effect across individuals. But the two models yield  
different estimates...?

My commands are as follows (I am working with a dichotomous response):

svyset cluster
svy:logit yesno var1 var2...

xtgee yesno var1 var2, i(cluster) link (logit) fam (bin)


I hope my problem is quite clear!


Best
