Diagrams showing the fraction of failure to predict as a function of the length of sliding time windows in which the catalogue is subdivided. The length is shown, on the X axis, normalized to the total length of the catalogue. Curves for different catalogues are shown with different colors (see also the text). The results shown here have been computed using the value for the proton density threshold ρT = 15.5 protons/cm3, which represents the optimal value, which minimizes the integral below the curve for the total catalogue. The value of the integral below each curve represents the total prediction failure fraction; it should be close to 0.5 for a random, non predictive model. The values found here are: 0.05 for the total catalogue; 0.05 for the ‘learning’ catalogue; 0.08 for the shallow events catalogue; 0.17 for the ‘testing’ catalogue; 0.21 for the deep events catalogue.
