Abstract:

Under the circumstances that the variance is uncertain, the Ustatistics testing method is proposed for any two populations. Furthermore, we discussed the consistency and asymptotic normality of test statistics and its efficacy.

Key words: Ustatistics, consistency, asymptotic normality, asymptotic relative efficiency
