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 149.8438253846154 > 142.342387045.
IsChangePoint: Marked as a change because one of 3/28/2022 9:07:19 PM, 3/31/2022 1:45:25 PM falls between 3/22/2022 11:55:12 PM and 3/31/2022 1:45:25 PM.
IsRegressionStdDev: Marked as regression because -10.27633589328017 (T) = (0 -159725539.02860475) / Math.Sqrt((5365423775.444562 / (42)) + (60857601959573.86 / (11))) is less than -2.007583770314729 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (42) + (11) - 2, .025) and -0.17831671568555896 = (135553995.71470433 - 159725539.02860475) / 135553995.71470433 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.
