Dear GSL Community,
Ran into a mysterious problem.
When I run gsl_ran_fdist_pdf(.012, 8, 249) I get infinity.
But when I run
gsl_ran_fdist_pdf(.012, 8, 248) I get .000074, which is correct (checked
against MATLAB and R)
one d.f. change makes this difference - but I don't see why it should from
the formula for F pdf.
i am running a Dell Latitude E6500 machine with ubuntu 9 linux , 64 bit and
gcc 4.4.1 . I built the gsl library from source for my system.
Please help!
Gunjan
