You probably have to have some idea of what functions might be
suitable for fitting. Otherwise you will have to go around looking for
a packages starting like this:

(* :Name: TOE` *)

(* :Author: God *)


But seriously, unless you have a strong suspicion of how the data are
distributed and you want to get a better understanding of that you
should probably start plotting them with different types of axes. Do
also try to simply plot data on paper and sketch curves that seems to
fit - by hand. It should not be too difficult to guess at some
suitable functions to do the fit. And it will also enable you to
narrow down the search space when looking for a suitable package.
