"In probability theory, Slutsky’s theorem extends some properties of algebraic operations on convergent sequences of real numbers to sequences of random variables. The theorem was named after Eugen Slutsky. Slutsky's theorem is also attributed to Harald Cramér. Visa mer This theorem follows from the fact that if Xn converges in distribution to X and Yn converges in probability to a constant c, then the joint vector (Xn, Yn) converges in distribution to (X, c) (see here).

WebbShowing Convergence in Distribution Recall that the characteristic function demonstrates weak convergence: Xn X ⇐⇒ Eeit T X n → Eeit T X for all t ∈ Rk. Theorem: [Levy’s Continuity Theorem]´ If EeitT Xn → φ(t) for all t in Rk, and φ : Rk → Cis continuous at 0, then Xn X, where Eeit T X = φ(t). Special case: Xn = Y . WebbIn Theorem 1 of the paper by [BEKSY] a generalisation of a theorem of Slutsky is used. In this note I will present a necessary and su–cient condition that assures that whenever X n is a sequence of random variables that converges in probability to some random variable X, then for each Borel function fwe also have that f(X n) tends to f(X) in

WebbABSTRACT. For weak convergence of probability measures on a product of two topological spaces the convergence of the marginals is certainly necessary. If however the marginals on one of the factor spaces converge to a one-point measure, the condition becomes sufficient, too. This generalizes a well-known result of Slutsky.
