Deviation and Moment Inequalities for Banach-Valued U-statistics

  • Davide Giraudo

摘要

We show a deviation inequality for U-statistics of independent data taking values in a separable Banach space which satisfies some smoothness assumptions. We then provide applications to rates in the law of large numbers for U-statistics, a Hölderian functional central limit theorem and a moment inequality for incomplete U-statistics.
