WebbThe Slutsky's theorem: Let { X n }, { Y n } be two sequences of scalar/vector/matrix random elements. If X n converges in distribution to a random element X and Y n converges in probability to a constant c, then X n + Y n → d X + c X n Y n → d c X X n / Y n → d X / c, provided that c is invertible, where → d denotes convergence in distribution. WebbSlutsky's Theorem - Proof Proof This theorem follows from the fact that if X n converges in distribution to X and Y n converges in probability to a constant c , then the joint vector ( X …

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).

"WebbIf X n tends to X a.s., then X n tends to X in probability. Fact 2. If X n tends to X in probability, it has a subsequence that tends to X a.s. Fact 3. Let ( a n) be a sequence of real numbers. Then ( a n) converges to a ∈ R if, and only if, every subsequence of ( a n) has a sub (sub)sequence that tends to a. " - Slutsky’s theorem
