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 23.35906192269433 > 21.68776366412728.
IsChangePoint: Marked as a change because one of 7/6/2022 5:19:04 PM, 9/20/2022 10:35:57 PM, 9/22/2022 3:16:12 AM falls between 9/13/2022 2:36:07 PM and 9/22/2022 3:16:12 AM.
IsRegressionStdDev: Marked as regression because -9.883905846979554 (T) = (0 -23.042569984878817) / Math.Sqrt((0.27813627779117395 / (49)) + (0.14508962573615755 / (4))) is less than -2.007583770314729 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (49) + (4) - 2, .025) and -0.09631454836709699 = (21.01821053017997 - 23.042569984878817) / 21.01821053017997 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.
