multivariate distribution是指的是衡量多个随机变量的分布吗？
NO.PZ2017092702000085 问题如下 Whiof the following assets most likely requires the use of a multivariate stribution for moling returns A.A call option on a bon B.A portfolio of technology stocks C.A stoin a market inx B is correct. Multivariate stributions specify the probabilities for a group of relateranm variables. A portfolio of technology stocks represents a group of relateassets. Accorngly, statisticinterrelationships must consire resulting in the neeto use a multivariate normstribution.对于多元分布来说，适用于“a group of ranm variables”，对于一个组合内有多个资产（变量）的情况比较适用，选 老师为什么不能选C
