Dear Statalist,
I am conducting some APC modelling but due to the original source of my data there is a prblem of identifiability (cohort=period-age!) To correct for this when modelling I was hoping to use -apc_ie-, the intrinsic estimator. However, it is unclear (in the help file and the paper written) on the format the data should be in before entering into -apc_ie-.
Would anyone be able to help on this? Or if not then suggest another method of correcting for identification in APC modelling?
BW,
Karen
