      public IndicatorResult(String indicator, double[] values)
      Constructs a new object for storing the results for a single indicator.
      Parameters:
      indicator - the name of the indicator
      values - the computed indicator values

  • Method Details

    • getValues

      public double[] getValues()
      Returns the computed indicator values.
      Returns:
      the indicator values

    • getMin

      public double getMin()
      Returns the minimum indicator value.
      Returns:
      the minimum indicator value

    • getMedian

      public double getMedian()
      Returns the median indicator value.
      Returns:
      the median indicator value

    • getMax

      public double getMax()
      Returns the maximum indicator value.
      Returns:
      the maximum indicator value

    • getStatistic

      public double getStatistic(org.apache.commons.math3.stat.descriptive.UnivariateStatistic statistic)
      Computes and returns the value of the given univariate statistic.
      Parameters:

    • display

      public void display(PrintStream ps)
      Description copied from interface: Displayable
      Displays the contents of this object to the given output stream. This method does not close the underlying stream; the caller is responsible for disposing it.
      Specified by:
      display in interface Displayable
      Parameters:
      ps - the output stream
