We establish (a) the probability mass function of the interpoint distance (IPD) between random vectors that are drawn from the multivariate power series family of distributions (MPSD); (b) obtain the distribution of the IPD within one sample and across two samples from this family; (c) determine the distribution of the MPSD Euclidean norm and distance from fixed points in \({\mathbb {Z}}^d\); and (d) provide the distribution of the IPDs of vectors drawn from a mixture of the MPSD distributions. We present a method for testing the homogeneity of MPSD mixtures using the sample IPDs.

多元幂级数点间距离

我们建立(a)从多元幂级数分布族(MPSD)得出的随机向量之间的点间距离(IPD)的概率质量函数;(b)获得IPD在该家庭的一个样本中以及在两个样本中的分布;(c)确定MPSD欧几里得范数的分布以及距\({\ mathbb {Z}} ^ d \)中的固定点的距离;(d)提供从MPSD分布的混合中得出的矢量的IPD分布。我们提出了一种使用样本IPD测试MPSD混合物均匀性的方法。
