Description of detection logic
IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsRegressionBase: Marked as regression because the compare was 5% greater than the baseline, and the value was not too small.
IsRegressionWindowed: Marked as regression because 1.1776707031839444 > 1.1522767137797745.
IsChangePoint: Marked as a change because one of 10/6/2022 12:41:43 AM, 10/17/2022 12:47:34 PM, 10/25/2022 2:56:59 AM falls between 10/16/2022 1:15:28 PM and 10/25/2022 2:56:59 AM.
IsRegressionStdDev: Marked as regression because -13.60071673730971 (T) = (0 -1234.3608447429528) / Math.Sqrt((668.10382189735 / (16)) + (1706.078661088532 / (29))) is less than -2.016692199226234 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (16) + (29) - 2, .025) and -0.12423605008193206 = (1097.9552244859922 - 1234.3608447429528) / 1097.9552244859922 is less than -0.05.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
