Asymptotic Efficiency of Goodness-of-fit Tests for the Power Function Distribution Based on Puri--Rubin Characterization
Power function distribution,U-statistics characterizations Bahadur efficiency
2012/9/18
We construct integral and supremum type goodness-of-fit tests for the family of power distribution functions. Test statistics are functionals of U−empirical processes and are based on the classi...
Goodness-of-Fit tests with Dependent Observations
Extreme value statistics Stochastic processes Models of financial markets
2011/7/7
We revisit the Kolmogorov-Smirnov and Cram\'er-von Mises goodness-of-fit (GoF) tests and propose a generalisation to identically distributed, but dependent univariate random variables. We show that th...
Improved estimator of the entropy and goodness of fit tests in ranked set sampling
Ordered Ranked set sampling Judgement ranking Order statistic Information theory
2011/7/5
The entropy is one of the most applicable uncertainty measures in many statistical and en- gineering problems. In statistical literature, the entropy is used in calculation of the Kullback- Leibler (K...
Multivariate Goodness of Fit Procedures for Unbinned Data: An Annotated Bibliography
Multivariate Goodness An Annotated Bibliography
2011/3/21
Unbinned maximum likelihood is a common procedure for parameter estimation. After parameters have been estimated, it is crucial to know whether the fit model adequately describes the experimental data...
A goodness-of-fit test for bivariate extreme-value copulas
extreme-value copula goodness of fi t parametric bootstrap Pickands dependence function rank-based inference
2011/3/21
It is often reasonable to assume that the dependence structure of a bivariate continuous distribution belongs to the class of extreme-value copulas. The latter are characterized by their Pickands depe...
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
stationary marked Gibbs point processes residuals goodness-of-fit test quadrat count-ing test maximum pseudolikelihood estimator
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 ...

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...

2009/9/16
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 in...
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...

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 ...
