Method Detail

• evaluate

  double evaluate(double[] values,
                double[] weights)
                  throws MathIllegalArgumentException

  Returns the result of evaluating the statistic over the input array, using the supplied weights.

  Parameters:

  values - input array

  weights - array of weights

  Returns:

  the value of the weighted statistic applied to the input array

  Throws:

  MathIllegalArgumentException - if either array is null, lengths do not match, weights contain NaN, negative or infinite values, or weights does not include at least on positive value

• evaluate

  double evaluate(double[] values,
                double[] weights,
                int begin,
                int length)
                  throws MathIllegalArgumentException

  Returns the result of evaluating the statistic over the specified entries in the input array, using corresponding entries in the supplied weights array.

  Parameters:

  values - the input array

  weights - array of weights

  begin - the index of the first element to include

  length - the number of elements to include

  Returns:

  the value of the weighted statistic applied to the included array entries

  Throws:

  MathIllegalArgumentException - if either array is null, lengths do not match, indices are invalid, weights contain NaN, negative or infinite values, or weights does not include at least on positive value
