cfS_Triangular: Characteristic function of Triangular distribution

Description Usage Arguments Value See Also Examples

Description

cfS_Triangular(t, a) evaluates the characteristic function cf(t) of the Triangular distribution on the interval (-a, a) with mode 0 (Triangular distribution with mean = 0 and variance = 1/18(2a^2 + a) cfS_Triangula(t, a) = (2 - 2cos(at)) / (a^2 * t^2)

Usage

1

Arguments

t

numerical values (number, vector...)

a

number, a > 0, default value a = 1
