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 we could not find enough baseline builds for window checking.
IsChangePoint: Marked as a change because one of 8/5/2022 12:58:40 PM, 10/6/2022 12:41:43 AM, 10/17/2022 3:19:47 PM, 10/19/2022 4:51:05 PM falls between 10/10/2022 11:56:05 PM and 10/19/2022 4:51:05 PM.
IsRegressionStdDev: Marked as regression because -8.340742740855228 (T) = (0 -1465.5622377774455) / Math.Sqrt((690.7713871981738 / (26)) + (2855.6693825126813 / (6))) is less than -2.0422724562973107 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (26) + (6) - 2, .025) and -0.1462336330881648 = (1278.5894563475254 - 1465.5622377774455) / 1278.5894563475254 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.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
