Hi,

I want to be able to specify a bunch of probabilities and get back the
inverse cdf from the standard normal distribution.. basically I want
to get back 0 if I specify 0.5 and so on. Is there any procedure to do
this? I also have the GQOPT library installed.

Thanks in advance for all your help.

Cheers
Seema

The best I know for this sort of questions is <http://www.netlib.org>
You will find all kinds of implementations of algorithms there.

cdflib90 (http://odin.mdacc.tmc.edu/anonftp/) is good, especially if you use
Fortran 90/95.

Or try dcdflib at www.netlib.org

Please use more informative subjects than "newbie question", for example
"invserse cumulative normal in Fortran".

Besides searching Netlib, as was suggested, another way to find a Fortran
code on subject "foo" is to use Google. In your case, Googling "inverse cumulative
normal filetype:f" produces many relevant hits.
