IDAX.QWILCOX - Inverse Wilcoxon distribution

The QWILCOX function returns the value x of a variable that follows the Wilcoxon distribution for which the probability of being smaller or equal to x is equal to the specified percentage.

Syntax

IDAX.QWILCOX(DOUBLE percentage, INT8 NoItems)

Parameter descriptions

percentage: Mandatory.; The requested limit of the percentage.; If percentage is not in the range of 0 - 1, QWILCOX(percentage,NoItems) is null for all NoItems values.; Min: 0.0000001; Max: 0.9999999; Data type: DOUBLE
NoItems: Mandatory.; The number of items.; If NoItems is not in the range of 1 - 15, QWILCOX(percentage,NoItems) returns null for all percentage values.; Min: 1; Max: 15; Data type: INT8

If PWILCOX(Wmin,NoItems)=perc, QWILCOX(perc,NoItems)=Wmin for all Wmin values and NoItems values in their respective validity interval.

Returned information

INT8 the point x where PWILCOX(x,NoItems)=percentage.
