Precise large deviations for dependent regularly varying sequences.
We study a precise large deviation principle for a stationary regularly varying sequence of random variables. This principle extends the classical results of A.V.... -
The cluster index of regularly varying sequences with applications to limit t...
We introduce the cluster index of a multivariate regularly varying stationary sequence and characterize the index in terms of the spectral tail process. This index... -

Selection Criteria in Regime Switching Conditional Volatility Models
A large number of non linear conditional heteroskedastic models have been proposed in the literature and practitioners do not have always the tools to choose the...
