fitting code, statistical library

[To Forum]

hi,
i am looking for a library in C++ which enables me to fit a function to a
set of data...ideally in pure STL C++...
Please share your insight on the subject.
my thanks
TF

Perhaps ROOT? It is not perhaps "pure STL C++" as you put it but anyway...

well, what do you mean by "but anyway..."
is there any thing better than root (which is highly adviced by my physicist
friends)

I meant: But anyway, if might be worth a try.

The mathematics behind "fitting functions" is logical as far as I know so
to define what is "better" and what is not so good is perhaps an issue of
calculation speed. If you know what function to fit, then perhaps the best
(the fastest with regards to calculation speed) solution is to derive your
own least squares measure of the fit and code it.
