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 112.52664760231312 > 106.46904325914913.
IsChangePoint: Marked as a change because one of 12/8/2022 9:11:55 AM, 1/11/2023 2:37:52 AM, 2/19/2023 8:14:07 AM, 2/21/2023 5:46:41 AM falls between 2/12/2023 2:35:10 PM and 2/21/2023 5:46:41 AM.
IsRegressionStdDev: Marked as regression because -13.027258951308566 (T) = (0 -110.3927897711911) / Math.Sqrt((0.4042938203688266 / (52)) + (5.142474481164312 / (10))) is less than -2.0002978220134566 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (52) + (10) - 2, .025) and -0.09320952255602948 = (100.98045021880353 - 110.3927897711911) / 100.98045021880353 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.
