Details:
Dear GSL,
I've encountered a potential bug in the routine "gsl_cdf_chisq_Pinv" defined
in the file gsl-1.11/cdf/chisqinv.c.
When calling this routine with the degrees of freedom > 1263131, I get the
following error message:
gsl: gamma_inc.c:99: ERROR: error
Default GSL error handler invoked.
Abort
For degrees of freedom <= 1263131, it seems to perform fine.
I'm running GSL version 1.11 and calling the routine as follows:
v = gsl_cdf_chisq_Pinv(0.05, nu);
where nu = the degrees of freedom.
Thanks,
John Halley Gotway
