IDAX.PEXP_H - High-tail cumulative exponential distribution

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

Syntax

IDAX.PEXP_H(DOUBLE x, DOUBLE scale)

x: Mandatory.; The value that is to be computed.; If x is negative, PEXP_H(x,scale) is null for all scale values.; Min: 0.00000000001; Data type: DOUBLE
scale: Mandatory.; The exponential scale.; If scale is 0 or less, PEXP_H(x,scale) is null for all x values.; Min: 0.00000000001; Data type: DOUBLE

PEXP_H(x,scale)=1-PEXP(x,scale) for all x values and df values.

DOUBLE the cumulative probability distribution from x to plus infinity.
