IDAX.DMWW - Density of the Mann-Whitney-Wilcoxon distribution

The DMWW function returns the value of the "probability density" (probability mass function) of the MWW distribution at point x. It returns the probability that the value of a variable that follows the MWW distribution is equal to MWWmin.

Syntax

IDAX.DMWW(INT8 MWWmin, INT8 COUNTmin, INT8
NoItems)

Parameter descriptions

MWWmin: Mandatory.; The value that is to be computed.; Min: 0; Max: COUNTmin*(NoItems+NoItems-COUNTmin+1)/2;; Data type: INT8
COUNTmin: Mandatory.; The number of items in set 1.; Min: 1; Max: NoItems-1; Data type: INT8
NoItems: Mandatory.; The total number of items.; Min: 1; Data type: INT8

DMWW(MWWmin,COUNTmin,NoItems)=PMWW(MWWmin,COUNTmin,NoItems) - PMWW(MWWmin-1,COUNTmin,NoItems) is applicable for all MWWmin, COUNTmin, and NoItems values in their respective validity interval.

If MWWmin, COUNTmin, or NoItems are not in their validity interval, DMWW(MWWmin,COUNTmin, NoItems) returns null.

Returned information

DOUBLE the probability density at point MWWmin.
