FNP_gaussreturns the value of the integral of the Gaussian, or normal, probability density function of meanmand standard deviations(represented below byσ) atx. The integral,P(x;m,σ), is defined by the expression
Pis defined for all values ofxandmand for positive values ofσ.
P(x;0,σ)
Errors
FNP_gausscauses an HTBasic error if its arguments are not all of type REAL or if the value ofSis negative or zero.
