How exactly does CEM calculate its baselines?
APM CE (CEM) baselines are calculated based on the algorithms below. To change the algorithms, modify the parameters in the tess-default.properties file and restart the EM. APM CE uses these values for Box-Whisker graphs.
The tess-default.properties file contains the following default settings:
baseline.durationInDays = 28
baseline.upper.discardOutlierPercentage = 5.0
baseline.upper.offsetPercentage = 20.0
baseline.lower.discardOutlierPercentage = 5.0
baseline.lower.offsetPercentage = 20.0
The upper baseline is calculated as follows:
The lower baseline is calculated as follows:
