IDAX.PWEIBULL_H - High-tail cumulative Weibull distribution

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

Syntax

IDAX.PWEIBULL_H(DOUBLE x, DOUBLE scale, DOUBLE
kShape)

Parameter descriptions

x
Mandatory.
The value that is to be computed.
Min: 0
Data type: DOUBLE
scale
Mandatory.
The scale of the distribution.
Min: 0.00000000001
Data type: DOUBLE
kShape
Mandatory.
The shape of the distribution.
Min: 0.00000000001
Data type: DOUBLE

PWEIBULL_H(x,scale,kShape)=1-PWEIBULL(x,scale,kShape) for all positive x values, positive scale values, and positive kShape values.

If x is less than 0, or if scale or shape are 0 or less, PWEIBULL_H(x,scale,kShape) is null.

Returned information

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