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 9.63240612988184 > 9.252880439142293.
IsChangePoint: Marked as a change because one of 3/17/2022 6:54:53 PM, 5/20/2022 7:26:52 AM, 5/26/2022 4:44:18 AM falls between 5/17/2022 2:28:28 PM and 5/26/2022 4:44:18 AM.
IsRegressionStdDev: Marked as regression because -14.15975450263905 (T) = (0 -9791.560434343146) / Math.Sqrt((2380.9791169829336 / (19)) + (108102.47519884912 / (23))) is less than -2.0210753903043583 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (19) + (23) - 2, .025) and -0.11167310099712986 = (8807.949410272207 - 9791.560434343146) / 8807.949410272207 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.
