Rqandall, let us listen Marcin first. Maybe he has some interesting informations. In fityk i found that the favourie mehtod is "chi squares method".
Gsl offers this also : — Function: double gsl_cdf_chisq_P (double x, double nu) — Function: double gsl_cdf_chisq_Q (double x, double nu) — Function: double gsl_cdf_chisq_Pinv (double P, double nu) — Function: double gsl_cdf_chisq_Qinv (double Q, double nu) On Monday, January 23, 2012 10:41:55 Randall Morgan wrote: > Looks to me that as long as any derivative work is lincesed GPL and we > follow it's terms we should be good to go with the fityk library. > > On Mon, Jan 23, 2012 at 10:18 AM, Randall Morgan <rmorga...@gmail.com>wrote: > > Wally, > > > > I just found this: http://fityk.nieto.pl/intro.html#about > > > > If you scroll down you'll find that the fityk library is licensed under > > the GPL 2 or later.
