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 170.36097705498125 > 160.33698231055433.
IsChangePoint: Marked as a change because one of 4/13/2022 5:30:39 PM, 4/19/2022 4:39:14 PM falls between 4/10/2022 11:44:05 PM and 4/19/2022 4:39:14 PM.
IsRegressionStdDev: Marked as regression because -18.89319053962743 (T) = (0 -172.4940018356465) / Math.Sqrt((10.34875968742592 / (31)) + (14.249642708594294 / (26))) is less than -2.0040447832881556 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (31) + (26) - 2, .025) and -0.11465117586726781 = (154.75155418145542 - 172.4940018356465) / 154.75155418145542 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.
