Adaptive semiparametric wavelet estimator and goodness-of-fit test for long memory linear processes
Statistics Theory (math.ST)
2010/12/17
This paper is first devoted to study an adaptive wavelet based estimator of the long memory parameter for linear processes in a general semi-parametric frame. This is an extension of Bardet {\it et al...
Adaptive estimator of the memory parameter and goodness-of-fit test using a multidimensional increment ratio statistic
Long-memory Gaussian processes goodness-of-fit test estimation of the memory parameter
2010/10/14
The Increment Ratio (IR) statistic was first defined and studied in Surgailis {\it et al.} (2008) for estimating the long-memory parameter either of a stationary or an increment stationary Gaussian p...
Residuals and goodness-of-fit tests for stationary marked Gibbs point processes

2010/3/10
The inspection of residuals is a fundamental step to investigate the
quality of adjustment of a parametric model to data. For spatial
point processes, the concept of residuals has been recently prop...
A goodness-of-fit test for parametric and semi-parametric models in multiresponse regression

2010/3/9
We propose an empirical likelihood test that is able to test the goodness of fit of a class of parametric and semi-parametric multiresponse regression models. The class includes as special cases

Nonparametric Estimation of Kullback-Leibler Information Illustrated by Evaluating Goodness of Fit
Goodness of Fit Kullback-Leibler Information Consistency
2009/9/22
We describe a method for quantifying the lack of t in a proposed
family of distributions. The method involves estimating the posterior distribu-
tion of the Kullback-Leibler information between the ...
STOCHASTIC VOLATILITY:APPROXIMATION AND GOODNESS-OF-FIT TEST
Non-parametric estimation goodness-of-fit test stochastic volatility discrete time observation
2009/9/18
Let X be the unique solution started from x0 of the stochastic
differential equation dXt = µ(t;Xt)dBt +b(t;Xt)dt with B a standard
Brownian motion. We consider an approximation of the volatili...
A framework is developed using techniques from
rate distortion theory in statistical testing. The idea is first to do
optimal compression according to a certain distortion function
and then use inf...

2010/3/19
We consider the goodness of fit testing problem for ergodic diffusion
processes. The basic hypothesis is supposed to be simple. The
diffusion coefficient is known and the alternatives are described ...

We consider the goodness of fit testing problem for stochastic differential
equation with small diffusion coefficient. The basic hypothesis
is always simple and it is described by the known trend co...

2010/3/18
We consider the problem of testing hypotheses on the copula density from n bidimensional
observations. We wish to test the null hypothesis characterized by a
parametric class against a composite non...

In the framework of quantum optics, we study the problem of
goodness-of-fit testing in a severely ill-posed inverse problem. A novel testing
procedure is introduced and its rates of convergence are ...

A goodness of fit test for the drift coefficient of an ergodic diffusion
process is presented. The test is based on the score marked empirical
process. The weak convergence of the proposed test stat...
