Definition of evaluation measures of Simulation 2 (Simulation 2 section).

Level Measure Notation Definition Description
Voxel False discovery rate vFDR
E([V10/V1·]I{V1·>0})
Expected value of the proportion of false positive voxels among all rejected voxels
Sensitivity vSens E(V1|1) / V·|1 Expected value of the proportion of truly active voxels that have been correctly rejected
Cluster Family-wise error rate cFWER P(C1|0 > 0) Probability of observing a family-wise error, which occurs when there are one or more false positive clusters per map

Note: We adopted the notational convention of Nichols and Hayasaka (2003) to define the measures (see Table 2 and Simulation 2 section). As defined in Nichols and Hayasaka (2003), I{A} is the indicator function for an event A.
