function [ n_data, sam, suc, pop, n, fx ] = hypergeometric_pdf_values ( n_data )

%*****************************************************************************80
%
%% hypergeometric_pdf_values() returns some values of the hypergeometric PDF.
%
%  Discussion:
%
%    PDF(X)(A,B) is the probability of X successes in A trials,
%    given that the probability of success on a single trial is B.
%
%    In Mathematica, the function can be evaluated by:
%
%      dist = HypergeometricDistribution [ sam, suc, pop ]
%      PDF [ dist, n ]

%
%  Input:
%
%    integer N_DATA.  The user sets N_DATA to 0 before the first call. 
%
%  Output:
%
%    integer N_DATA.  On each call, the routine increments N_DATA by 1, and
%    returns the corresponding data; when there is no more data, the
%    output value of N_DATA will be 0 again.
%
%    integer SAM, integer SUC, integer POP, the sample size, 
%    success size, and population parameters of the function.
%
%    integer N, the argument of the function.
%
%    real FX, the value of the function.
