cdfs.eps: These are the cumulative distributions for station PALO for one hour each on day 135(Notremor) and day 137(Tremor). The S statistic distributions are clearly distinct, while the MSQDFC distributions are much less so. Spdfs.eps: shows the probability distributions for S (the derivative of the cdfs of the previous figure. MSQDFCpdfs.eps: Same as previous but for MSQDFC. ROCS.eps The Receiver Operating Characteristic for the S statistic. ROCDFC.eps: The ROC for MSQDFC. These figures indicate that S should be a better detector, however, we have additional information, in the form of Justin Brown's picks. The fact that the MSQDFC is bounded by 1 while S is not makes comparison difficult. My first attempt at a comparison is to use his picks as delta functions to sample the values of the two statistics at the times of his picks (actually I used the origin times, which may be problematic). I then compared this to the mean values of S and MSQDFC for that hour. The S sampling produced a number less than the mean while the sampling MSQDFC produced a number higher than the mean, which would seem to contradict the analysis using ROCs. The plots of this comparison are incomplete. Any suggestions for better tests would be appreciated.
