Reciprocal Mill's Ratio
...I rather expected. I wonder if anyone has dug out a function for the reciprocal Mill's ratio out of the pnorm() code? Anticipating the obvious response I don't believe that this would be one of the things I might be good at! Murray Jorgensen References Cody, W. D. (1993) Algorithm 715: SPECFUN ?

bug in pnorm (PR#699)
...h, which was pointed out in a second article published three years after the original. The error was that a macro/variable named SIXTEN had a value of 1.6e0 instead of the correct 1.6e1 (that is, 16 not 1.6). The author of the code for R (Ross Ithaka?) must have worked from an outdated version of SPECFUN and not the corrected one that now appears in CALGO, STATLIB, et cetera. There is a macro in pnorm.c (in the nmath directory) which looks like: #define SIXTEN 1.6 /* Magic Cutoff */ It should be something like: #define SIXTEN 16.0 /* Magic Cutoff */ I know this appears in R version 1.1.1. I know...

Modified Bessel function (third kind)
Hi: There is a Modified Bessel function (third kind, real order) besselK in R. Is there a C version of this function? I can only find a Fortran function rkbesel on http://www.netlib.org/specfun/. However, this rkbesel fortran function is the second kind. Thank you! liu _______________________________ Declare Yourself - Register online to vote today!
