报告摘要 Abstract: We introduce a new measure for testing independence between two random vectors. Our measure differs from that of distance covariance, by using expected conditional difference of characteristic functions. We propose one empirical version by slicing on one of the random vectors. We show that this particular version is equivalent to DISCO (Rizzo and Szêkely, 2010). This empirical measure is based on certain Euclidean distance. Its properties, asymptotic and applications in testing independence are discussed. Implementation and Monte Carlo results are also presented.(Joint work with my student: Qingcong Yuan)
