其实,这种直觉的背后是有理论支撑的,那就是大数定理(Law of Large Numbers)。大数定理有两种形式:弱大数定理(Weak Law of Large Numbers)和强大数定理(Strong Law of Large Numbers)。这篇文章主要推导了弱大数定理。 1.弱大数定理的形式定义 独立同分布 ...

这背后是大数定理（Law of Large Numbers）的理论支撑，它包含弱大数定理（Weak Law of Large Numbers）和强大数定理（Strong Law of Large Numbers）。弱大数定理主要描述了在独立同分布（independent and identically distributed）条件下，随机变量序列的平均值将趋于其期望值。具体表述为：对于独立同分布的...
