IDAX.PFISK_H - High-tail cumulative Fisk distribution

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

Syntax

IDAX.PFISK_H(DOUBLE x, DOUBLE median, DOUBLE
shape)

x: Mandatory.; The value that is to be computed.; Min: 0.000000001; Data type: DOUBLE
median: Mandatory.; The median value of the distribution.; This value is also called scale.; Min: 0.000000001; Data type: DOUBLE
shape: Mandatory.; The shape of the distribution.; Min: 0.000000001; Data type: DOUBLE

PFISK_H(x,median,shape)= 1-PFISK(x,median,shape) for all positive x values, positive median values, and positive shape values.

If x, median or shape is 0 or less, PFISK_H(x,median,shape) is null.

DOUBLE the cumulative probability distribution from x to plus infinity.
