Asymptotic properties of the maximum likelihood and cross validation estimators for transformed Gaussian processes
François Bachoc, José Bétancourt, Reinhard Furrer +1
The asymptotic analysis of covariance parameter estimation of Gaussian processes has been subject to intensive investigation. However, this asymptotic analysis is very scarce for n…
On agnostic post hoc approaches to false positive control
Gilles Blanchard, Pierre Neuvial, Etienne Roquain
This document is a book chapter which gives a partial survey on post hoc approaches to false positive control.
Sensitivity Analysis and Generalized Chaos Expansions. Lower Bounds for Sobol indices
O Roustant, F. Gamboa, B Iooss
The so-called polynomial chaos expansion is widely used in computer experiments. For example, it is a powerful tool to estimate Sobol' sensitivity indices. In this paper, we consid…
Large scale in transit computation of quantiles for ensemble runs
Alejandro Ribes, Théophile Terraz, Bertrand Iooss +2
The classical approach for quantiles computation requires availability of the full sample before ranking it. In uncertainty quantification of numerical simulation models, this appr…
Adjacency-constrained hierarchical clustering of a band similarity matrix with application to Genomics
Christophe Ambroise, Alia Dehman, Pierre Neuvial +2
Motivation: Genomic data analyses such as Genome-Wide Association Studies (GWAS) or Hi-C studies are often faced with the problem of partitioning chromosomes into successive region…
New statistical methodology for second level global sensitivity analysis
Anouar Meynaoui, Amandine Marrel, Béatrice Laurent
Global sensitivity analysis (GSA) of numerical simulators aims at studying the global impact of the input uncertainties on the output. To perform the GSA, statistical tools based o…
