UnivariateStatistic with
increment and incrementAll(double[]) methods for adding
values and updating internal state.
This interface is designed to be used for calculating statistics that can be computed in one pass through the data without storing the full array of sample values.
| Modifier and Type | Method and Description |
|---|---|
| public void | |
| public StorelessUnivariateStatistic | Returns: a copy of the statisticRedeclares org. Returns a copy of the statistic with the same internal state. |
| public long | |
| public double | Returns: value of the statistic,Double.NaN if it
has been cleared or just instantiated.Returns the current value of the Statistic. |
| public void | increment(double
the new value. d)Updates the internal state of the statistic to reflect the addition of the new value. |
| public void | incrementAll(double[]
array holding the new values to add values)Updates the internal state of the statistic to reflect addition of all values in the values array. |
| public void | incrementAll(double[]
array holding the new values to add values, int the array index of the first value to add start, int the number of elements to add length)Updates the internal state of the statistic to reflect addition of the values in the designated portion of the values array. |
| clear | back to summary |
|---|---|
| public void clear() Clears the internal state of the Statistic | |
| copy | back to summary |
|---|---|
| public StorelessUnivariateStatistic copy() Redeclares org. Returns a copy of the statistic with the same internal state.
| |
| getN | back to summary |
|---|---|
| public long getN() Returns the number of values that have been added.
| |
| getResult | back to summary |
|---|---|
| public double getResult() Returns the current value of the Statistic.
| |
| increment | back to summary |
|---|---|
| public void increment(double d) Updates the internal state of the statistic to reflect the addition of the new value.
| |
| incrementAll | back to summary |
|---|---|
| public void incrementAll(double[] values) throws MathIllegalArgumentException Updates the internal state of the statistic to reflect addition of all values in the values array. Does not clear the statistic first -- i.e., the values are added incrementally to the dataset.
| |
| incrementAll | back to summary |
|---|---|
| public void incrementAll(double[] values, int start, int length) throws MathIllegalArgumentException Updates the internal state of the statistic to reflect addition of the values in the designated portion of the values array. Does not clear the statistic first -- i.e., the values are added incrementally to the dataset.
