Change-point tests for the tail parameter of Long Memory Stochastic Volatility time series
Annika Betken, Davide Giraudo, Rafał Kulik
We consider a change-point test based on the Hill estimator to test for structural changes in the tail index of Long Memory Stochastic Volatility time series. In order to determine…
Bound on the maximal function associated to the bounded law of the iterated logarithms via orthomartingale approximation
Davide Giraudo
We give sufficient conditions for the bounded law of the iterated logarithms for strictly stationary random fields when the summation is done on rectangle. The study is done by the…
An exponential inequality for -statistics of i.i.d. data
Davide Giraudo
We establish an exponential inequality for degenerated -statistics of order of i.i.d. data. This inequality gives a control of the tail of the maxima absolute values of the…
Large deviation inequalities for martingales in Banach spaces
Xiequan Fan, Davide Giraudo
Let be a martingale difference sequence in a smooth Banach space. Let be the partial sums of $(X_i, \mathcal{F}_i)_{…
Limit theorems for U-statistics of Bernoulli data
Davide Giraudo
In this paper, we consider U-statistics whose data is a strictly stationary sequence which can be expressed as a functional of an i.i.d. one. We establish a strong law of large num…
