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 95.93109802871611 > 95.91787767326292.
IsChangePoint: Marked as a change because one of 2/12/2022 1:03:18 PM, 3/17/2022 6:54:53 PM, 4/19/2022 10:22:09 AM, 4/26/2022 6:18:08 AM falls between 4/17/2022 3:25:40 PM and 4/26/2022 6:18:08 AM.
IsRegressionStdDev: Marked as regression because -11.91126647080833 (T) = (0 -96.25047299345033) / Math.Sqrt((1.6864977905789762 / (22)) + (2.948181854969924 / (36))) is less than -2.0032407188469383 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (22) + (36) - 2, .025) and -0.051830822217544925 = (91.50756087421759 - 96.25047299345033) / 91.50756087421759 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.
