I have a query about post-estimation of ORs (and CIs) after logistic
regression using -svrmodel-.
I am using data from the Australian Bureau of Statistics with replicate
weights. I have built a logistic regression model which includes a
couple of interaction terms (between 3 dichotomous variables of interest
and the dummy variables for different age groups). I would like to
calculate ORs with confidence intervals for the different age groups vs
reference category for the variables with significant interactions. I
tried using -lincom-:
lincom var, or
lincom var + var_age25, or
lincom var + var_age35, or
lincom var + var_age45, or
lincom var + var_age55, or
But was left with the error message: unrecognized command: svysvrmodel
I have used the post-estimation -test- command with no such problems.
I could calculate the ORs manually, but would have trouble with
calculating the CIs that way.
Thanks for any help.
