Average amount of hours per day that the prediction system records a Hit (H), occurrence (O) or that the system is inside the subcluster (I) for variable severity label (for example: A value of 0.4 at row I, subcluster 2 and column G means that on average, 0.4 hours of green days are inside subcluster 2).

We also present the Peirce Skill score (PSS) for each subcluster and days. Capital characters in header refer to green (G), neutral (N), red (R) and black (B) days. Parameter settings: pc = 0.08, ϵ = 30 minutes and tmax = 90 minutes.
