Next: Two-level GLM Up: tr01cb1 Previous: Introduction


To begin with we consider the familiar two-level univariate GLM for FMRI. That is, the model that in the first level deals with individual subjects, relating time-series to activation, and in the second level deals with a group of subjects or sessions (or both), relating the combined individual activation estimates to some group parameter, such as mean activation level.
