IDAX.PHYPER_H - High-tail cumulative hypergeometric distribution

The PHYPER_H function returns the probability that the value of a variable that follows the geometric distribution is greater than x.

Syntax

IDAX.PHYPER_H(BIGINT x, BIGINT wu, BIGINT bu, BIGINT
N)

x: Mandatory.; The number of white balls that are drawn without replacement from an urn that contains black balls and white balls.; Data type: BIGINT
wu: Mandatory.; The number of white balls in the urn.; If wu is negative, PHYPER_H(x,wu,bu,N) is null for all x values and N values.; Min: 0; Data type: BIGINT
bu: Mandatory.; The number of black balls in the urn.; If bu is negative, PHYPER_H(x,wu,bu,N) is null for all x values and N values.; Min: 0; Data type: BIGINT
N: Mandatory.; The number of balls that drawn from the urn without replacement.; If N is 0 or less, PHYPER_H(x,wu,bu,N) is null for all x values, wu values, and bu values.; Min: 1; Data type: BIGINT

PHYPER_H(x,wu,bu,N) = 1-PHYPER(x,wu,bu,N) for all x values, positive wu values, positive bu values, and positive N values.

DECFLOAT(16) for the cumulative probability distribution from x to plus infinity.
