ASA241 is a FORTRAN77 library which computes the inverse of the Normal Cumulative Density Function (CDF), by Michael Wichura;
ASA241 is Applied Statistics Algorithm 241. Source code for many Applied Statistics Algorithms is available through STATLIB.
The library includes two routines, PPND7, and PPND16, suitable for single or double precision arithmetic calculations.
ASA241 is available in a C version and a C++ version and a FORTRAN77 version and a FORTRAN90 version and a MATLAB version.
ASA066, a FORTRAN77 library which evaluates the CDF of the normal distribution.
ASA111, a FORTRAN77 library which evaluates the percentage points of the Normal distribution.
DCDFLIB, a FORTRAN90 library which contains routines for evaluating and inverting the normal CDF, and many other distributions.
PROB, a FORTRAN90 library which contains routines for evaluating and inverting the normal CDF, and many other distributions.
TEST_VALUES, a FORTRAN77 library which contains routines that store selected values of the normal CDF, and many other statistical distributions.
