The Response Screening report consists of a results table and several plots. These plots focus on False Discovery Rate (FDR) statistics. See The False Discovery Rate.
The default plots are the FDR PValue Plot, the FDR LogWorth by Effect Size, and the FDR LogWorth by RSquare. If you select the Robust option on the launch window, Robust versions of each of these reports are also presented. In addition, a Robust LogWorth by FDR LogWorth plot is presented to help assess the impact of using the robust fit.
