P_gauss

Probability integral for Gaussian distribution.

Loading LOADSUB ALL FROM "ERF.HTS"

or LOADSUB FROM "MATHLIB.HTS"

Usage REAL X,M,S,Y

Y=FNP_gauss(M,S,X)

Description

FNP_gauss returns the value of the integral of the Gaussian, or normal, probability density function of mean m and standard deviation s (represented below by σ) at x. The integral, P(x;m,σ), is defined by the expression

P is defined for all values of x and m and for positive values of σ.

P(x;0,σ)

Errors

FNP_gauss causes an HTBasic error if its arguments are not all of type REAL or if the value of S is negative or zero.
