Input VariableCapacity to Detect OutliersComments
Speed variationVery highAll the replicas including only speed variation are categorized as outliers
Vibration introductionVery highAll the replicas including only vibration variation are categorized as outliers
MisalignmentHigh2 out of 3 replicas clearly categorized as outliers
BrakeLowAll replicas are <85% of outliers but >60%
