This score is meant to be abstract representation of how important this alert is compared to the others. There are many factors that go into generating a score: | |||
* The p-value of the test used, | |||
* a multiplier for the type of test (compensating for it's propensity to send false alerts), | |||
* the relative size of the regression, and | |||
* in the case of compound alerts; a mixture of the component alert scores. | |||
Right now, The score currently maps to the p-value of the median test used to detect the regression: <code>score = -log10(p-value)</code>. It is currently set to alert when score > 2 (p-value < 0.01), and does not go above 4 (p-value > 0.0001) given the current window size. | |||
