Notes from the OHBM 2015 "Statistical Assessment of MVPA Results" Morning Workshop

Thanks to everyone that attended and gave feedback on the OHBM morning workshop "Statistical Assessment of MVPA Results" that Yaroslav Halchenko and I organized! We've received several requests for slides and materials related to the workshop, so I'll collect them here. It appears that material from the meeting will also be searchable from links on the main OHBM 2015 page. As always, all rights are reserved, and we expect to be fully cited, acknowledged, and consulted for any uses of this material.

I started the workshop off with a tutorial on permutation testing aimed at introducing issues particularly relevant for MVPA (and neuroimaging datasets in general). I'll eventually post a version of the slides, but some of the material is already available in more detail in two PRNI conference papers:

• Etzel, J.A. 2015. MVPA Permutation Schemes: Permutation Testing for the Group Level. 5th International Workshop on Pattern Recognition in NeuroImaging (PRNI 2015). Stanford, CA, USA. In press, full text here, and in ResearchGate.
• Etzel, J.A., Braver, T.S., 2013. MVPA Permutation Schemes: Permutation Testing in the Land of Cross-Validation. 3rd International Workshop on Pattern Recognition in NeuroImaging (PRNI 2013). IEEE, Philadelphia, PA, USA. DOI:10.1109/PRNI.2013.44. Full text here, and in ResearchGate.

Next, Johannes Stelzer gave a talk entitled "Nonparametric methods for correcting the multiple comparisons problem in classification-based fMRI", the slides for which are available here.

Then, Nikolaus Kriegeskorte gave a talk entitled "Inference on computational models from predictions of representational geometries", the slides for which are available here.

Finally, Yaroslav Halchenko finished the session with a talk giving an "Overview of statistical evaluation techniques adopted by publicly available MVPA toolboxes", the slides for which are available here.
