By coincidence Bugs is being mentioned on the
mailing list, and I am doing some statistics (not my strong point).

Can someone point me to a reference that explains how to
compute the percentile points of the Chi^2 cumulative distribution
function?

I am currently using a numerical root finder (LibSolve) to invert
the incomplete gamma function ratio (LibGamma), but suspect that there
must be a much better way.


Apologies for troubling people with what is not really a BlackBox
question.

Regards

Robert
