Dear experts,
I would like to kindly ask your help in the interpretation of a regression output. A refrence categor of an intereraction is empty and one of the other category is omitted, both by the Stata automatically in my logit regression
How do I interpret the coefficients for the interaction in the presence of these two problems: the first category is empty, and the fifth category is omitted?
Do I interpret the coefficients with respect to the base of the omitted group? what about the empty one? It seems to me that this groups is empty because of lack of observations in that particular intersection, but how do ignoring this empty group affect the interpretation of the coefficients.
Thank you in advance
