Sigma threshold
WebSigma 0.85 = 30 days Sigma (standard deviation) threshold is calculated using inputs such as deviation from baseline, cluster confidence, number of valid and invalid clusters, and baseline value. The sigma is a deviation from the established baseline. WebUse the slider to specify a value for Flag as Violations when Rarity Crosses Sigma Threshold Value. Example: 0.85. For this analytic technique, the Sigma Threshold Value indicates the time for which the system suppresses the identification of an alert. Higher sigma values indicate that a system should wait "x" days before identifying an alert.

If your measurement is more than three standard deviations away from your average, this measurement is considered an anomaly. But as illustrated in the image above, you still have a 0.1% probability that your prediction was incorrect; and that the measurement was, in fact, an expected value.
