Cram\'{e}r-type moderate deviations for Studentized two-sample $U$-statistics with applications

open access: yes, 2016
Two-sample $U$-statistics are widely used in a broad range of applications, including those in the fields of biostatistics and econometrics. In this paper, we establish sharp Cram\'{e}r-type moderate deviation theorems for Studentized two-sample $U ...
