| AbstractUnivariateStatistic | | abstract public class AbstractUnivariateStatistic implements UnivariateStatistic,Serializable(Code) | | Abstract base class for all implementations of the
UnivariateStatistic interface.
Provides a default implementation of evaluate(double[]),
delegating to evaluate(double[], int, int) in the natural way.
Also includes a test method that performs generic parameter
validation for the evaluate methods.

| Method Summary | |
| public double | evaluate(double[] values)
| | abstract public double | evaluate(double[] values, int begin, int length)
| | protected boolean | test(double[] values, int begin, int length)
This method is used by evaluate(double[], int, int) methods
to verify that the input parameters designate a subarray of positive length. |
| test | | protected boolean test(double[] values, int begin, int length)(Code) | | This method is used by evaluate(double[], int, int) methods
to verify that the input parameters designate a subarray of positive length.
- returns
true iff the parameters designate a subarray of
positive length
- throws
IllegalArgumentException if the array is null or
or the indices are invalid
- returns
false if the array is non-null, but
length is 0.
Parameters:
values - the input array
Parameters:
begin - index of the first array element to include
Parameters:
length - the number of elements to include true if the parameters are valid and designate a subarray of positive length
throws:
IllegalArgumentException - if the indices are invalid or the array is null |
