 org.apache.commons.math.stat.descriptive.rank.Min
| Min | | public class Min extends AbstractStorelessUnivariateStatistic implements Serializable(Code) | | Returns the minimum of the available values.
- The result is
NaN iff all values are NaN
(i.e. NaN values have no impact on the value of the statistic).
- If any of the values equals
Double.NEGATIVE_INFINITY,
the result is Double.NEGATIVE_INFINITY.
Note that this implementation is not synchronized. If
multiple threads access an instance of this class concurrently, and at least
one of the threads invokes the increment() or
clear() method, it must be synchronized externally.

| Method Summary | |
| public void | clear()
| | public double | evaluate(double[] values, int begin, int length)
Returns the minimum of the entries in the specified portion of
the input array, or Double.NaN if the designated subarray
is empty.
Throws IllegalArgumentException if the array is null or
the array index parameters are not valid.
- The result is
NaN iff all values are NaN
(i.e. | | public long | getN()

| evaluate | | public double evaluate(double[] values, int begin, int length)(Code) | | Returns the minimum of the entries in the specified portion of
the input array, or Double.NaN if the designated subarray
is empty.
Throws IllegalArgumentException if the array is null or
the array index parameters are not valid.
- The result is
NaN iff all values are NaN
(i.e. NaN values have no impact on the value of the statistic).
- If any of the values equals
Double.NEGATIVE_INFINITY,
the result is Double.NEGATIVE_INFINITY.
Parameters:
values - the input array
Parameters:
begin - index of the first array element to include
Parameters:
length - the number of elements to include the minimum of the values or Double.NaN if length = 0
throws:
IllegalArgumentException - if the array is null or the array indexparameters are not valid |
