Webwhere we have taken the argument of the characteristic function to be k instead of θ, which is a standard notation in the continuous case. Mathematically this characteristic function is the Fourier transform of the probability density p(x). Note that one important property of the characteristic function is λ(0) = ∞ −∞ p(x)dx =1, WebJan 1, 2014 · The characteristic function (c.f.) of a probability distribution function (d.f.) is the Fourier–Stieltjes transform of the d.f. More precisely, if F is a probability d.f. on d -dimensional real space R d ( d ≥ 1), then its c.f. is a complex function ϕ : R d → C such that for any t = ( t 1, …, t d ) ∈ R d,
