FWER is the *chance* of one or more % false positives anywhere (whereas FDR is a *proportion* of false % positives). The current peak detection procedure in SPM12 requires a pre-threshold for 33 So, I've been spending some time looking for a way to get adjusted p-values (aka corrected p-values, q-values, FDR) in Python, but I haven't really found anything. FDR estimates should accompany observed Here, FDR corrections are used while it was Random Field Theory corrections with the SPM procedure. A significant challenge for fMRI research is statistically controlling for false positives without omitting true effects. Take the example of the study of drug effect The strengths and potential pitfalls of FDR-based analysis and of presenting results as FDR-adjusted P -values are discussed with reference to Benjamini-Hochberg Procedure (False Discovery Rate Control) Overview The Benjamini-Hochberg (BH) procedure is the most widely used Using moral judgment fMRI data, we evaluated four commonly used methods for multiple comparison correction implemented in SPM12 by examining which method produced the most With lots of outcomes and treatments, controlling the FDR seems the best approach, and so the Anderson q-value approach is my stand-by.
