Overflow from Alan Miller's Fortran web site
Includes updates of some TOMS algorithms, logistic regression, a Fortran 90 version of the special functions from the NSWC (Naval Surface Warfare Center) Math. Library, quadruple precision using 10-byte reals for the NAS Fortran-Plus compiler giving about 38 decimal digit accuracy, and code for Imagine1's F compiler, including the author's least-squares package. F code should compile using any standard Fortran compiler.
