IDAX.QUNIF_H - High-tail inverse uniform distribution

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

Syntax

IDAX.QUNIF_H(DOUBLE percentage, DOUBLE minimum, DOUBLE
maximum)

Parameter descriptions

percentage
Mandatory.
The requested limit of the percentage.
If percentage is not in the range of 0 - 1, QUNIF_H(percentage,minimum,maximum) is null for all minimum values and maximum values.
Min: 0.00000000001
Max: 0.99999999999
Data type: DOUBLE
minimum
Mandatory.
The left border of the uniform interval.
If minimum is not smaller than maximum, QUNIF_H(percentage,minimum,maximum) is null for all percentage values.
Max: <maximum>
Data type: DOUBLE
maximum
Mandatory.
The right border of the uniform interval.
Min: <minimum>
Data type: DOUBLE

QUNIF_H(percentage,minimum,maximum)=QUNIF(1-percentage,minimum,maximum) for percentage values in the range of 0 - 1, and for all minimum values and maximum values, where minimum < maximum.

If PUNIF_H(x,minimum,maximum)=perc, QUNIF_H(perc,minimum,maximum)=x for all x, values, minimum values, and maximum values, where x is between minimum and maximum.

Returned information

DOUBLE the point x where PUNIF_H(x,minimum,maximum)=percentage.
