For this study, the individuals are a convenience sample from
households that participated in a case-control "parent" study in which
the case households had contaminated water and control households did

This cross-sectional study includes all of the adults within the case
and control households who consented to participate by completing the
individual questionnaire.


Brenda,  Please give some detail about the survey design: 1. What was
the target population; 2. How did you select the sample-please give
all steps.

Greetings from a new Statalister.
I am in need of advice, including references, if you have any.

We have done a household-level cross-sectional survey including all consenting adults within the household (1 to 4 per cluster). There are both household-level and personal-level variables.
The dependent variable is nominal at the personal level (ill/not ill).
The focal independent variable is nomial and at the household level (water contaminated/not).
Other variables of interest (explanatory, in relation to focal independent variable) are at the personal and household level.

My question is I need to use GEE to adequately account for clustering within households OR would the svy:logit in Stata do this? (The ICC for illness & household is 0.08, SE 0.08)
