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 835.9670565422779 > 832.516955221402.
IsChangePoint: Marked as a change because one of 9/28/2022 6:40:13 PM, 11/28/2022 8:15:19 AM, 12/1/2022 1:41:45 AM falls between 11/22/2022 11:24:47 AM and 12/1/2022 1:41:45 AM.
IsRegressionStdDev: Marked as regression because -167.38465038153453 (T) = (0 -836.9050241259916) / Math.Sqrt((1.469526424058317 / (31)) + (0.1686847417776245 / (9))) is less than -2.0243941639098457 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (31) + (9) - 2, .025) and -0.05422864804341138 = (793.855323206441 - 836.9050241259916) / 793.855323206441 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.
