If you type within Stata -help fracpoly- or -help mfp- you will get the
help file of these programs. These tell you whether it can be applied
to longitudinal data. (The answer is yes, but in a limited way)

-mfracpol- by Patrick Royston published in the Stata Technical Bulletin
(predecessor of the Stata Journal) seems pretty old and looks like it
is superseded by the official Stata command -mfp-.
