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 15.765435302648601 > 14.616556880016617.
IsChangePoint: Marked as a change because one of 2/23/2022 1:54:47 PM, 2/26/2022 10:27:55 AM, 4/16/2022 2:55:52 PM, 4/20/2022 10:05:23 PM falls between 4/12/2022 9:30:02 AM and 4/20/2022 10:05:23 PM.
IsRegressionStdDev: Marked as regression because -13.288274646308315 (T) = (0 -16.542613122958947) / Math.Sqrt((0.30559218329145393 / (26)) + (0.3500244291239915 / (15))) is less than -2.0226909200346674 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (26) + (15) - 2, .025) and -0.1771200313369502 = (14.05346326845714 - 16.542613122958947) / 14.05346326845714 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.
