Slutsky’s theorem
WebbA Donsker class is Glivenko–Cantelli in probability by an application of Slutsky's theorem. These statements are true for a single f {\displaystyle f} , by standard LLN , CLT arguments under regularity conditions, and the difficulty in the Empirical Processes comes in because joint statements are being made for all f ∈ F {\displaystyle f\in {\mathcal {F}}} . WebbTheorem 1 (Slutsky) If Xn⇒ X, Y ⇒ yoand his continuous from S1 × S2 to S3 at x,yo for each xthen Zn= h(Xn,Yn) ⇒ Z= h(X,y) 5. We will begin by specializing to simplest case: S is the real line and d(x,y) = x− y . In the following we …

If Ynprob → c, for any constant c, and Xndist → X then: 1.) Xn + Yndist → Xn + c 2.) XnYndist → cX. Proof of 1.) Let x be a point such that x − c is a point of continuity of Fx and pick ϵ such that x − c + ϵ is another point of continuity of Fx.

WebbThe Slutsky’s theorem allows us to ignore low order terms in convergence. Also, the following example shows that stronger impliations over part (3) may not be true.
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).
