I'd like to see if I have this straight, since this is one of my first
times using postestimation tests of coefficients in any serious way.
Using Stata 8
The relevant variables are:
sex coded 0=female 1=male
colon coded 0=no 1=yes (any colonic symptoms)
colonmale = colon*sex (an interactive term)
sdq_hyp is the dependent variable
after -svyregress- that uses these (among others) as independent
variables, I figure that
-lincom colon- gives the effect of being a girl with colon symptoms
-lincom colon sex colonmale- gives the effect of being a boy with colon
Do I have that correct?
I get stumped with -adjust-
can I type -adjust age=6, by(colon sex)- to get the effects of the 4
different combinations of sex and colon, in 6 year old kids? Or do I
need to put the colonmale term in there somewhere?
I have a similar question regarding these commands after svyologit.
Thanks.
