摘要设X1,X2,…,Xn为身份证明。RP中的随机向量,其中p趋于无穷大。给出了当p2/n趋于零时中心极限定理成立的一个定理。在此基础上,给出了具有混合多元正态分布(具有有限矩母函数)且对样本均值的分布具有一致正态逼近的例子 $$(\SQRT{\Text{n}}\上划线{\Text{X}})$$ 如果p2/n不趋向于零,则不能保持。
SummaryLet X1, X2, ..., Xn be i.i.d. random vectors in Rp where p tends to infinity. A theorem is presented showing that the Central Limit Theorem should hold if p2/n tends to zero. Furthermore, an example is presented with Xi having a mixed multivariate normal distribution (with finite moment generating function) for which a uniform normal approximation to the distribution of the sample mean $$(\sqrt {\text{n}} \overline {\text{X}} )$$ can not hold if p2/n does not tend to zero.
