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 23.61168895807073 > 22.837756753456883.
IsChangePoint: Marked as a change because one of 8/22/2022 7:03:36 PM, 8/23/2022 8:42:14 PM, 10/13/2022 5:34:08 PM, 10/18/2022 1:35:00 AM falls between 10/7/2022 9:25:17 PM and 10/18/2022 1:35:00 AM.
IsRegressionStdDev: Marked as regression because -6.085062324448584 (T) = (0 -24.325940808166493) / Math.Sqrt((0.7757410226159789 / (38)) + (1.3026125884528592 / (16))) is less than -2.0066468050606243 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (38) + (16) - 2, .025) and -0.08674742611217663 = (22.384171541304863 - 24.325940808166493) / 22.384171541304863 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.
