Delete the first part. It was stated that the indvar is 0,1. But why
then the two different styles? -xi:- is unnecessary scaffolding in that
case.

Subject: RE: help: bootstrap with GEE in stata
I believe that
xtgee depvar indvar
and
xi: xtgee depvar i.indvar
do not in general imply the same model, so why the surprise?
In addition, which model assumes that depvar is unconditionally normal?

I am running these two types of commands in stata:
bootstrap, reps(200): xtgee depvar indvar, fam(normal) link(id)
i(case_no) t(week1_10) robust
xi: xtgee depvar i.indvar, fam(normal) link(id) i(case_no) t(week1_10)
vce(bootstrap, reps(200))
The two commands give similar results for some of the variables, but for
some of the variables I get very different results with respect to
significance, for most of the variables I get significant results with
the 1st command given above.
The dependent variables are of very complex nature and does not follow
the assumption of normality, independent variable is a categorical(0,1)
