【Abstract】 This article brings forward the conception of universal gravitation in sample space via the thought of the universal gravitation in astrospace, and gives its applications on the discriminate analysis. The gravitational discrimination has more comprehensive adaptability and higher correct rates of back substitution compared to other discriminations such as Bayes’, Dstance’s and Fisher’s.更多还原
