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 54.95063085387325 > 52.09670164183033.
IsChangePoint: Marked as a change because one of 10/6/2022 12:41:43 AM, 10/17/2022 12:47:34 PM, 10/18/2022 8:25:03 PM falls between 10/7/2022 9:25:17 PM and 10/18/2022 8:25:03 PM.
IsRegressionStdDev: Marked as regression because -14.546448372851367 (T) = (0 -54292.109505447355) / Math.Sqrt((3861900.3285391256 / (45)) + (195855.23542561987 / (4))) is less than -2.011740513728388 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (45) + (4) - 2, .025) and -0.1090958437801724 = (48951.684211890606 - 54292.109505447355) / 48951.684211890606 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.
