Dear all,

I am analysing three datasets, each of which
are from the same population bu different years, 
say 2002, 2003 and 2004, but not longitudinally

The number of cases of a disease (numb_of_cases),
the population size (popul)
the degree of exposure (exposure)
are recorded in each of 1000 towns. 

The incidence (number of cases per
population) is about 1/1000 per year.

Initially, I used such commands as
.glm numb_of_cases exposure if year==2002, f(b popul)
.glm numb_of_cases exposure if year==2003, f(b popul)
.glm numb_of_cases exposure if year==2004, f(b popul)

Q1. I would like to bundle these three years
into one analysis.  "cluster" option is
available for such a command as "regress",
but not for "glm".  How could this analysis
be clustered?

Q2.  I was suggested that
familly binomial may not be adequate;
logistic or poisson regression may be more
suitable.  What commands can be used for
the above settings?

Let me apologise to you for these lay
