Researchers have developed a new method for analyzing high-dimensional U-statistics, which are complex statistical measures used in various fields including econometrics. The approach provides an order-explicit large deviation bound, detailing the maximum deviation between a U-statistic and its Hájek projection. This advancement includes novel moment inequalities and leads to improved concentration and Gaussian approximation results for these statistics. The findings have practical applications in establishing the consistency of resampling-based confidence intervals for nonparametric regression estimators, such as those used in random forests. AI
