摘要:We consider the same problem as in Kamiya and Takemura(1997), but for discriminant analysis on(n-1)-dimensional unit sphere Sn-1. That is, we regard pairwise discriminant analysis of m populations on Sn-1 as a process to generate rankings among the populations, and give a formula for the number of generated rankings.
