摘　　要：设X～EC_9(U_1,Σ,φ),即X服从椭球等高布分;X_1,X_2,…,X_n是来自X的样本,作 T_0~2=((?)-u)′Σ^(-1)((?)-u),((?)=1/n sum from i=1 to n (X_i))本文将在一定条件下,给出T_0~2的密度函数。Let X be a p-dimension random variable, and X-EOo(μ,Σ, (φ)),that is, the characteristic function of X is(?)((t-μ)'Σ(t-μ)).x1,…, Xn are samples from X. In this paper we obtain the density function of under some assumptions.
