IDAX.QWILCOX_H - High-tail inverse Wilcoxon distribution

The QWILCOX_H function returns the value x of a variable that follows the Wilcoxon distribution for which the probability of being greater than x is equal to the specified percentage.

Syntax

IDAX.QWILCOX_H(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_H(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_H(percentage,NoItems) returns null for all percentage values.
Min: 1
Max: 15
Data type: INT8

QWILCOX_H(perc,NoItems)=QWILCOX(1-perc,NoItems) for all perc values and NoItems values in their respective validity interval.

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

Returned information

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