Method Detail

getActualMaximum

public double getActualMaximum()

Description copied from interface: OutlierScoreMeta

Get the actual maximum of the value range.

Specified by:

getActualMaximum in interface OutlierScoreMeta

Returns:

maximum or Double.NaN

getActualMinimum

public double getActualMinimum()

Description copied from interface: OutlierScoreMeta

Get the actual minimum of the value range.

Specified by:

getActualMinimum in interface OutlierScoreMeta

Returns:

minimum or Double.NaN

getTheoreticalBaseline

public double getTheoreticalBaseline()

Description copied from interface: OutlierScoreMeta

Get the theoretical baseline of the value range. It will be common to see Double.POSITIVE_INFINITY here.

Specified by:

getTheoreticalBaseline in interface OutlierScoreMeta
