IDAX.PF_H - High-tail cumulative Fisher distribution

The PF_H function returns the probability that a variable that follows the Fisher distribution is greater than x.

Syntax

IDAX.PF_H(DOUBLE x, INT8 dfNomin, INT8 dfDenom)

Parameter descriptions

x
Mandatory.
The value that is to be computed.
Min: 0.00000000001
Data type: DOUBLE
dfNomin
Mandatory.
The number of degrees of freedom for the nominator.
Min: 1
Data type: INT8
dfDenom
Mandatory.
The number of degrees of freedom for the denominator.
Min: 1
Data type: INT8

PF_H(x,dfNomin,dfDenom)= 1-PF(x,dfNomin,dfDenom) for all positive x values, positive dfNomin values, and positive dfDenom values.

If x, dfNomin or dfDenom is 0 or less, PF(x,dfNomin,dfDenom) is null.

Returned information

DOUBLE the cumulative probability distribution from x to plus infinity.
