HypergeometricGraphData

public HypergeometricGraphData(int aN,
                               int aR,
                               int an,

                               int aI1)

constructs HypergeometricGraphData

Parameters:

aN - is the population size (positive integer)

aR - is the "special" population size (positive integer <= N)

an - is the sample size (positive integer <=N)

aI0 - is the left end of the probability interval

aI1 - is the right end of the probability interval
