Example operating characteristic. Operating points shown summarize the performance of LibSELDI and MassSpecWavelet on Dataset 2 of HYBRID1 for many different parameter choices. Each blue diamond is the (FDR, TPR) observed for a single choice of Peak Area threshold for LibSELDI, while each red plus symbol shows the result of a single Snr.Th parameter choice for MassSpecWavelet. For this particular example, LibSELDI finds more than 90 true proteins before making a mistake. At high FDR conditions, MassSpecWavelet resolves close to 90% of proteins compared to about 85% for LibSELDI.
