| Abstract: | One of the important steps to analyze brain imaging data is to determine the activation region of brain by hypothesis test. Single test method and some classical multiple test methods can not give out a good solution to multiple test problem in analyzing brain imaging data. A new multiple test method, false discovery rate (FDR) method, can get best result by controlling the rate of falsely rejected hypothesis. FDR method and other test methods are used to analyze simulation and fMRI data. The results prove that FDR method is a more creditable multiple test method. |
