Subject: Inverse normal distribution given p, µ and σ
Currently Math::Cephes::ndtri only takes on argument. It is desirable to calculate the inverse normal probability distribution for p (probability), µ (mean) and σ (standard deviation).

Well, judging by libmd/ndtri.c ndtri() in Cephes only takes one argument, so we mirror that API. However, I don't rule out coding a layer above that (in Perl or in XS) that will achieve what you describe. So patches are welcome. Regards, -- Shlomi Fish
