Analysis of family-wise error rates in statistical parametric mapping using random field theory
Abstract
This technical report revisits the analysis of family-wise error rates in statistical parametric mapping - using random field theory - reported in (Eklund et al., 2015). Contrary to the understandable spin that these sorts of analyses attract, a review of their results suggests that they endorse the use of parametric assumptions - and random field theory - in the analysis of functional neuroimaging data. We briefly rehearse the advantages parametric analyses offer over nonparametric alternatives and then unpack the implications of (Eklund et al., 2015) for parametric procedures.
Fwiw there's a response to an earlier (preprint) version of that paper from some of the developers of the packages in question. Preprint version of the "Cluster failure" paper, from last year: http://arxiv.org/abs/1511.01863 Response: http://arxiv.org/abs/1606.08199
