Limit theorems for nondegenerate U-statistics of continuous semimartingales
This paper presents the asymptotic theory for nondegenerate UUU-statistics of high frequency observations of continuous Itô semimartingales. We prove uniform convergence in probability and show a functional stable central limit theorem for the standardized version of the UUU-statistic. The limiting...

| Summary: | This paper presents the asymptotic theory for nondegenerate UUU-statistics of high frequency observations of continuous Itô semimartingales. We prove uniform convergence in probability and show a functional stable central limit theorem for the standardized version of the UUU-statistic. The limiting process in the central limit theorem turns out to be conditionally Gaussian with mean zero. Finally, we indicate potential statistical applications of our probabilistic results. |
