Practical use of permutations.() 1 - - (Full article) Many permutation examples use an independent variable with two conditions, and they permute these conditions for each subject for each electrode, and take the maximum t value across electrodes in each permutation, repeating this process 1000 times, and get a tmax distribution, then finding the 95th percentile value as a threshold. This way they control for false discovery rate across electrodes. Some other methods use cluster based method, where they use the spatial proximity of the electrodes and find the minimum electrode cluster size as a threshold. This method considers dependence between electrodes, but overlooks the small but significant clusters. But, all these methods assume simple two condition cases, swapping condition values for permutation test. 2 - Permutation – b
