Dear Statalisters:
I think it is more of a statistical question, but may I ask it:
If I have a categorical variable (letīs say with 4 categories) and run
the logistic regression _logistic depvar category2 category3 category4_,
I get the odds ratios relating each of the 2,3,4 categories against the
category1 reference, with straigthway interpretation. What is the
interpretation if I do _logistic depvar category3 category4_?
Sorry if it is a silly question.
Regards,
Jose Maria
