Block-threshold-adapted Estimators via a Maxiset Approach

Autin, Florent; Freyermuth, Jean-Marc; Sachs, Rainer Von - In: Scandinavian Journal of Statistics 41 (2014) 1, pp. 240-258

type="main" xml:id="sjos12012-abs-0001" <title type="main">ABSTRACT</title>We study the maxiset performance of a large collection of block thresholding wavelet estimators, namely the horizontal block thresholding family. We provide sufficient conditions on the choices of rates and threshold values to ensure that the...

Spatio-Spectral Mixed-Effects Model for Functional Magnetic Resonance Imaging Data

Kang, Hakmook; Ombao, Hernando; Linkletter, Crystal; … - In: Journal of the American Statistical Association 107 (2012) 498, pp. 568-577

The goal of this article is to model cognitive control related activation among predefined regions of interest (ROIs) of the human brain while properly adjusting for the underlying spatio-temporal correlations. Standard approaches to fMRI analysis do not simultaneously take into account both the...
