On Random Sequences with Centred Spherical Symmetry
研究了无限实随机变量序列，其中任意有限样本具有中心球面对称联合分布，并证明在给定两个随机变量M和V的条件下，序列中的变量独立同分布于正态分布N(M, V)。
SUMMARY An infinite sequence of real random variables, any finite sample from which has a centred spherically symmetric joint distribution, is shown to have the property that, conditional on two further random variables, M and V, the variables are independent with the same normal distribution N(M, V).
