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 43.894984671787704 > 30.216427792291704.
IsChangePoint: Marked as a change because one of 6/2/2022 12:41:31 AM, 6/7/2022 9:00:42 AM falls between 5/29/2022 5:15:01 PM and 6/7/2022 9:00:42 AM.
IsRegressionStdDev: Marked as regression because -67.55426562077355 (T) = (0 -44452.910097712476) / Math.Sqrt((1284770.026738758 / (37)) + (539136.6577802796 / (34))) is less than -1.9949454151066512 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (37) + (34) - 2, .025) and -0.519244133769709 = (29259.88595882297 - 44452.910097712476) / 29259.88595882297 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 as regression because Edge Detector said so.
