摘要
Let (X-1, Y-1),..., (X-N, Y-N) be independent identically distributed random vectors. We show that if the statistics L-X = beta X-1(1) + ... + beta X-N(N) and L-Y = beta Y-1(1) + ... + beta Y-N(N) are e-independent, then under some conditions, X = (X-1,..., X-N) and Y = (Y-1,..., Y-N) are epsilon(alpha)-independent for some alpha > 0.
