Interface PSquarePercentile.PSquareMarkers

Enclosing class:
PSquarePercentile
protected static interface PSquarePercentile.PSquareMarkers
An interface that encapsulates abstractions of the P-square algorithm markers as is explained in the original works. This interface is exposed with protected access to help in testability.

  • Method Details

    • getPercentileValue

      double getPercentileValue()
      Returns Percentile value computed thus far.
      Returns:
      percentile

    • copySelf

      PSquarePercentile.PSquareMarkers copySelf()
      A deep copy function to clone the current instance.
      Returns:
      deep copy of this instance

    • height

      double height(int markerIndex)
