math might be right, but this is not always enough. Excluding Anomalies Below the Thresholds • A change in very small numbers (0.005 – 0.5) is mathematically significant. • Yet, it is very case specific, becoming an interesting anomaly! Dormant Resources • Resources who does very little work – mostly inactive • A sudden, even subtle change in the performance can generate anomaly • In most cases this is not a critical resource to alert for These resources are not excluded from the learning, only from the results
