cfX_Normal: Characteristic function of Normal distribution

Description Usage Arguments Value See Also Examples

Description

cfX_Normal(t, mean, variance) evaluates the characteristic function cf(t) of the Normal distribution with mean = mean and variance = variance: N(mean, variance)) cfX_Normal(t, mean, variance) = exp(imeant -1/2variance^2t^2)

Usage

1
cfX_Normal(t, mean = 0, variance = 1)

Arguments

t

numerical values (number, vector...)

mean

real number, mean or expextation of the distribution, default value mean = 0

variance

real number, standard deviation, variance > 0, default value variance = 1

Value

characteristic function cf(t) of the normal distribution
