This library contains routines to compute cumulative distribution
functions, inverses, and parameters of the distribution for the
following set of statistical distributions:

    (1) Beta
    (2) Binomial
    (3) Chi-square
    (4) Noncentral Chi-square
    (5) F
    (6) Noncentral F
    (7) Gamma
    (8) Negative Binomial
    (9) Normal
    (10) Poisson
    (11) Student's t
    (12) Noncentral t

Given values of all but one parameter of a distribution, the other is
computed.  These calculations are done with double precision C
variables.
