On characterization of two-sample U-statistics

A verifiable condition for a symmetric statistic to be a two-sample U-statistic is given. As an illustration, we characterize which linear rank statistics with two-sample regression constants are U-statistics. We also show that invariance under jackknifing characterizes a two-sample U-statistic.
