Abstract:
We give sufficient conditions for the large deviations
principle of real valued von Mises statistics, improving
previous results. As a consequence
we obtain sufficient conditions for the large deviations principle for
Banach space valued $U$-statistics, improving previous results as well.
The proofs are based on large deviations results for
stochastic processes due to Arcones and a spectral decomposition
of the kernel function of the von Mises statistic and the
$U$-statistic, respectively.
Keywords:large deviations, $U$-statistics, von Mises statistics, stochastic processes.
