摘要
设π_1、π_2分别是具有分布密度的球分布,本文在一定的条件下证明了π_1与π_2的Kullback信息函数是π_1与π_2的马氏(Mahalanobis)距离的单调增加函数。
Let π1 and π2 be two populations with spherical densities. It is proved under certain conditions that the Kullback Information of π1 and π2 is a monotonically increasing function of the Mahalanobis distance between the two
