On the tails of the distribution of the maximum of a smooth stationary gaussian process

Jean-Marc AzaïsJean-Marc BardetMario Wschebor — 2002

ESAIM: Probability and Statistics

We study the tails of the distribution of the maximum of a stationary gaussian process on a bounded interval of the real line. Under regularity conditions including the existence of the spectral moment of order 8, we give an additional term for this asymptotics. This widens the application of an expansion given originally by Piterbarg [11] for a sufficiently small interval.

The likelihood ratio test for general mixture models with or without structural parameter

Jean-Marc AzaïsÉlisabeth GassiatCécile Mercadier — 2009

ESAIM: Probability and Statistics

This paper deals with the likelihood ratio test (LRT) for testing hypotheses on the mixing measure in mixture models with or without structural parameter. The main result gives the asymptotic distribution of the LRT statistics under some conditions that are proved to be almost necessary. A detailed solution is given for two testing problems: the test of a single distribution against any mixture, with application to Gaussian, Poisson and binomial distributions; the test of the number of populations...

Bounds and asymptotic expansions for the distribution of the Maximum of a smooth stationary Gaussian process

Jean-Marc AzaïsChristine Cierco-AyrollesAlain Croquette — 2010

ESAIM: Probability and Statistics

This paper uses the Rice method [18] to give bounds to the distribution of the maximum of a smooth stationary Gaussian process. We give simpler expressions of the first two terms of the Rice series [3,13] for the distribution of the maximum. Our main contribution is a simpler form of the second factorial moment of the number of upcrossings which is in some sense a generalization of Steinberg 's formula ([7] p. 212). Then, we present a numerical application and asymptotic expansions...
