Functions needed in the compution of the statistical F-test.

(March, 1990)
The enclosed functions are used in conjunction with computing
the statistical F-test.
The three m-files "betai.m", "betacf.m", and "gammln.m" are
direct analogs of the subroutines of the same name given in
Press et al., Numerical Recipes, Cambridge, 1986.

These files were written from scratch or converted from their
"Numerical Recipes" Fortran equivalents by:
