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 3.244571523529412 > 2.9803953254687507.
IsChangePoint: Marked as a change because one of 5/5/2022 2:36:12 AM, 5/9/2022 6:32:22 AM falls between 4/30/2022 6:29:51 PM and 5/9/2022 6:32:22 AM.
IsRegressionStdDev: Marked as regression because -11.754416497632137 (T) = (0 -3368770191.1844263) / Math.Sqrt((9693724322276770 / (27)) + (20906504443517576 / (13))) is less than -2.0243941639098457 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (27) + (13) - 2, .025) and -0.18309461673868646 = (2847422466.0668 - 3368770191.1844263) / 2847422466.0668 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.
