Slutsky's theorem convergence in probability
Webb极限定理是研究随机变量列的收敛性,在学习中遇到了随机变量列的四种收敛性:几乎处处收敛(a.e.收敛)、以概率收敛(P-收敛)、依分布收敛(d-收敛)、k阶矩收敛,下面是对它们的吐血整理。考虑一个随机变量列{δn},c为一个常数。由于随机性不能直接刻画收敛性,因此这4种收敛性都是在 ...

WebbSlutsky's theorem is based on the fact that if a sequence of random vectors converges in distribution and another sequence converges in probability to a constant, then they are … 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 .
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. Webb13 dec. 2004 · We shall denote by → p and → D respectively convergence in probability and in distribution when t→∞. Theorem 1 Provided that the linearization variance estimator (11) is design consistent and under regularity assumptions that are given in Appendix A , the proposed variance estimator (2) is also design consistent, i.e.
WebbNote. In this section we define convergence in distribution by considering the limit of a sequence of cumulative distribution functions. We relate convergence in probability and convergence in distribution (see Example 5.2.B and Theorem 5.2.1). We state several theorems concerning convergence in distribution of sequences of random variables.

Theorem: xn θ => xn θ Almost Sure Convergence ipo copyright phIn 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.
