-apc_ie- is a user-written program.  If you type -findit apc_ie- you
will see that in addition to the program and associated help file, there
is also an example dataset and do-file.  If you download these you will
see how the data are organised.

The do-file repeats an analysis reported in Table 3 of the paper by Yang
et al. (2004).

Subject: st: Age-period-cohort modelling, correcting for
identifcation-apc_ie-

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
