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 82.0464796875 > 60.35382775.
IsChangePoint: Marked as a change because one of 4/14/2022 12:09:31 PM, 4/16/2022 5:36:25 PM, 4/17/2022 8:26:34 PM, 4/19/2022 4:39:14 PM falls between 4/10/2022 11:44:05 PM and 4/19/2022 4:39:14 PM.
IsRegressionStdDev: Marked as regression because -13.492523916293859 (T) = (0 -80259257.30902778) / Math.Sqrt((82300629641282.98 / (50)) + (1584032126586.7437 / (6))) is less than -2.0048792881871513 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (50) + (6) - 2, .025) and -0.3026534945859573 = (61612130.65684657 - 80259257.30902778) / 61612130.65684657 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.
