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 12.611276363670004 > 8.183525362767785.
IsChangePoint: Marked as a change because one of 10/26/2022 7:11:30 AM, 11/1/2022 10:15:31 AM falls between 10/23/2022 1:14:54 PM and 11/1/2022 10:15:31 AM.
IsRegressionStdDev: Marked as regression because -35.25211814755959 (T) = (0 -11.46909107970713) / Math.Sqrt((0.006840580727820924 / (25)) + (0.2897007455461371 / (27))) is less than -2.0085591120996775 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (25) + (27) - 2, .025) and -0.47583294510231 = (7.771266468720857 - 11.46909107970713) / 7.771266468720857 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.
