The error seems to happen in the cephes library (the library we use for many functions in scipy.special, including this one). I don't know exactly what triggers it (your df is quite high, though, and the cdf is already quite past the 1-eps at your point). cheers, David _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
