摘要:
Consider the ratios U = X/Z, V = Y/Z where X, Y, Z are random variables. We first propose examples where X, Y are independent and (X, Y), Z are dependent, but U, V are independent. This is followed by an example where X, Y are dependent and (X, Y), Z are dependent, but U, V are independent. These examples broaden the scope of Mukhopadhyay and Son (2013). (C) 2014 Elsevier B.V.
