Statistical Analysis of fMRI Time-Series: A Critical Review of the GLM Approach

open access: yesFrontiers in Human Neuroscience, 2011
Functional Magnetic Resonance Imaging (fMRI) is one of the most widely used tools to study the neural underpinnings of human cognition. Standard analysis of fMRI data relies on a General Linear Model (GLM) approach to separate stimulus induced signals ...

Robust statistical methods: a primer for clinical psychology and experimental psychopathology researchers [PDF]

open access: yes, 2017
This paper reviews and offers tutorials on robust statistical methods relevant to clinical and experimental psychopathology researchers. We review the assumptions of one of the most commonly applied models in this journal (the general linear model, GLM ...

Quantitative Analysis of Arterial Spin Labeling FMRI Data Using a General Linear Model [PDF]

open access: yes, 2010
Arterial spin labeling techniques can yield quantitative measures of perfusion by fitting a kinetic model to difference images (tagged-control). Because of the noisy nature of the difference images investigators typically average a large number of tagged

Generalized Linear Models outperform commonly used canonical analysis in estimating spatial structure of presence/absence data [PDF]

open access: yesPeerJ, 2020
Background Ecological communities tend to be spatially structured due to environmental gradients and/or spatially contagious processes such as growth, dispersion and species interactions.
