I have data from different sources and need to use the source as a selection variable in an ordinal regression (only for the dependent variable, not for the regressors!).
I know how to do this for a linear regression. Is there a way to do this for ordinal regressions as well?
(I am researching whether past online ratings for retail stores influence future ratings.
I have a dataset of approx. 800.000 ratings. The unit of analysis is the rating given by person i to store s.)
Thanks for the help!
