Hi,
I am running the following regression:
looping over a list of variables. For some of the variables in the list, due to collinearity, coefficients of categorical variables i. Protection, i.Consulting and/or i.both do not exist (_b[1.Protection] for example if it is omitted).
I was wondering if there is a way to check if a coefficient exists (similar to capture confirm for variables)?
Thank you
