WebSep 5, 2024 · I then run a Wilcoxon rank sum test to compare, for each behaviour, the averages of durations, obtaining 12 p values, some of which are significant (values lower than alpha=0.05 ) The reviewer says that I need to correct alpha with Bonferroni, as I'm performing a multiple testing. This leads alpha to be very low: alpha corrected = 0.05/12 …

WebApr 11, 2016 · We know that we must apply Benjamini Hochberg-like corrections for multiple hypothesis testing to experiments based on a single data set, in order to control the false discovery rate, otherwise all experiments that give a positive result could be false.. But why don't we apply this same principle to all experiments since the beginning of time, … WebIn the analysis of fMRI data, many use small volume correction (SVC, as implemented in SPM) to restrict their search area to a given region of interest.
