IDAX.PBETA_H - High-tail cumulative beta distribution

The PBETA_H function returns the probability that the value of a variable that follows the beta distribution is greater than x.

Syntax

IDAX.PBETA_H(DOUBLE x, DOUBLE shapeOne, DOUBLE shapeTwo)

Parameter descriptions

x
Mandatory.
The value that is to be computed.
Data type: DOUBLE
shapeOne
Mandatory.
The first shape of the distribution.
Min: 0.00000000001
Data type: DOUBLE
shapeTwo
Mandatory.
The second shape of the distribution.
Min: 0.00000000001
Data type: DOUBLE

PBETA_H(x,a,b)=1-PBETA(x,a,b), for all x values, and for all positive a values and positive b values.

If a or b is 0 or less, PBETA_H(x,a,b) is null for all x values.

Returned information

DOUBLE the cumulative probability distribution from minus infinity to point x.
