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 8.030410526077464 > 7.043604040334799.
IsChangePoint: Marked as a change because one of 11/11/2022 8:39:50 AM, 11/16/2022 10:12:48 PM falls between 11/8/2022 2:29:58 AM and 11/16/2022 10:12:48 PM.
IsRegressionStdDev: Marked as regression because -5.198937503781661 (T) = (0 -9.00878454039609) / Math.Sqrt((0.3394596898528978 / (20)) + (2.5582812148615304 / (16))) is less than -2.0322445093148245 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (20) + (16) - 2, .025) and -0.32048090594953765 = (6.822351235679557 - 9.00878454039609) / 6.822351235679557 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.
