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.
IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsRegressionWindowed: Marked as regression because 24.260317557881482 > 21.467619909142417.
IsChangePoint: Marked as a change because one of 1/31/2022 1:37:35 PM, 2/1/2022 5:51:01 AM falls between 1/23/2022 2:39:24 PM and 2/1/2022 5:51:01 AM.
IsRegressionStdDev: Marked as regression because -27.429216259968307 (T) = (0 -23.97864052999163) / Math.Sqrt((0.403977404141772 / (75)) + (0.059125059664990244 / (4))) is less than -1.991254395387924 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (75) + (4) - 2, .025) and -0.19395673620667156 = (20.08334121567448 - 23.97864052999163) / 20.08334121567448 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.
