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 11.673458873056996 > 11.40710197571364.
IsChangePoint: Marked as a change because one of 11/10/2022 12:18:51 PM, 11/17/2022 1:45:21 AM falls between 11/8/2022 10:18:07 AM and 11/17/2022 1:45:21 AM.
IsRegressionStdDev: Marked as regression because -3.3762641098259167 (T) = (0 -14054.742486295354) / Math.Sqrt((6791847.042161181 / (16)) + (2526695.3674517255 / (20))) is less than -2.0322445093148245 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (16) + (20) - 2, .025) and -0.21697036877868336 = (11548.960309033893 - 14054.742486295354) / 11548.960309033893 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.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
