利用Weak Convergence证明Kolmogorov型强大数律

A New Proof for a Strong Law of Large Numbers of Kolmogorov's Type via Weak Convergence

Yu-Lin Chou

摘要:

利用样本均值的Dirac表示和经验分布几乎必然成立的弱收敛性,构造了一个具有独立同分布的Kolmogorov型强大数律的新证明.随机变量$X_{1}, X_{2}, \dots$使得$\lim_{c \to \infty}\sup_{n \in \mathbb{N}}n^{-1}\sum_{i=1}^{n}|X_{i}|\cdot \mathbb{I}_{[c,+\infty[}\circ |X_{i}| = 0$几乎必然。每个随机变量$X_{i}$都是$L^{1}$也是一个结论。我们的证明独立于Kolmogorov强定律及其已知的证明,并可能提供一种新的方法来获得Kolmogorov强定律的简短证明。

英文摘要:

In terms of the Dirac representation of sample mean and the weak convergence of empirical distributions that holds almost surely, we construct a new proof for a strong law of large numbers of Kolmogorov's type with i.i.d. random variables $X_{1}, X_{2}, \dots$ such that $\lim_{c \to \infty}\sup_{n \in \mathbb{N}}n^{-1}\sum_{i=1}^{n}|X_{i}|\cdot \mathbb{I}_{[c,+\infty[}\circ |X_{i}| = 0$ almost surely. That each random variable $X_{i}$ is $L^{1}$ is also a conclusion. Our proof is independent of both Kolmogorov's strong law and its known proof(s), and potentially furnishes a new way to obtain a short proof of Kolmogorov's strong law.
