Description of detection logic
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.
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 432.3213288174694 > 369.40213977708316.
IsChangePoint: Marked as a change because one of 12/17/2022 10:44:50 PM, 1/5/2023 4:05:11 PM, 3/28/2023 2:42:21 AM, 4/3/2023 11:26:06 PM falls between 3/26/2023 5:20:11 AM and 4/3/2023 11:26:06 PM.
IsRegressionStdDev: Marked as regression because -68.38777246847454 (T) = (0 -431.3038780888255) / Math.Sqrt((14.354857948249476 / (17)) + (9.151852881197419 / (20))) is less than -2.0301079282477414 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (17) + (20) - 2, .025) and -0.22089025466174744 = (353.2699818365902 - 431.3038780888255) / 353.2699818365902 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.
