Proof: 略 值得注意的是,这里 tightness 的作用是保证子集最终是收敛到一个 probability measure,即 \lim_{n\to +\infty}F_n(x)-\lim_{n\to-\infty}F_n(x)=1. 直观的说法就是,概率质量不会逃逸到无穷处的点上。所以有接下来的推论。 Proposition 5.5 (Neccessity of Tigtness) If \mu_n\Rightarr...
Several remarks about this theorem are in order at this point. First, no restrictions were put on the distribution of the Xi. The preceding proof applies to any infinite sum of IID random variables, regardless of the distribution. Also, the central limit theorem guarantees that the sum converge...
Theorem 1 – Central Limit Theorem: Ifxhas a distribution with meanμand standard deviationσthen fornsufficiently large, the variable has a distribution that is approximately the standard normal distribution.

We first give Lindeberg’s proof of the central limit theorem, based on exchanging (or swapping) each component of the sum in turn. This proof gives an accessible explanation as to why there should be a universal limit for the central limit theorem; one then computes directly with gaussians...

We prove the Central Limit Theorem (CLT) from the definition of weak convergence using the Haar wavelet basis, calculus, and elementary probability. The use of the Haar basis pinpoints the role of $L^{2}([0,1])$ in the CLT as well as the assumption of finite variance. We estimate ...
A Martingale Central Limit Theorem We will prove the following version of the martingale central limit theorem: Theorem 1. Let X n,k , 1 ≤ k ≤ m n be a martingale difference array with respect to F n,k and let S n,k = k i=1 X n,i . If Emax j≤mn |X n,j |→0 an...
