Calculates statistical cumulative distribution functions (P-values their inverses, and parameters of the distributions). Distributions include Incomplete Beta, Binomial, Negative Binomial, Chi-square, Non-central Chi-square, F, Non-central F, Incomplete Gamma, Normal, Poisson, and T. Program uses double precision library, DCDFLIB. Packaging changed to allow entry of user's choice of X or 1-X where appropriate and display of both. This allows calculations of p-values quite near one and accurate cdf values that are also close to 1.

Look at the readme file from the program.
