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 3.372689348081043 > 3.1353992043973635.
IsChangePoint: Marked as a change because one of 5/29/2022 1:12:49 PM, 6/2/2022 5:13:37 AM falls between 5/24/2022 3:42:52 PM and 6/2/2022 5:13:37 AM.
IsRegressionStdDev: Marked as regression because -2.484821071939381 (T) = (0 -6838.3149356847625) / Math.Sqrt((3563273.8545618057 / (31)) + (12326176.786408262 / (13))) is less than -2.0180817028167235 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (31) + (13) - 2, .025) and -0.5991260055470683 = (4276.282739423867 - 6838.3149356847625) / 4276.282739423867 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.
