| * <h4>UnivariateStatistic:</h4> |
| * <code>/∗ evaluation approach ∗/<br> |
| * double[] values = new double[] { 1, 2, 3, 4, 5 };<br> |
| * <span style="font-weight: bold;">UnivariateStatistic stat = new Mean();</span><br> |
| * out.println("mean = " + <span style="font-weight: bold;">stat.evaluate(values)</span>);<br> |
| * </code> |
| * |
| * <h4>StorelessUnivariateStatistic:</h4> |
| * <code>/∗ incremental approach ∗/<br> |
| * double[] values = new double[] { 1, 2, 3, 4, 5 };<br> |
| * <span style="font-weight: bold;">StorelessUnivariateStatistic stat = new Mean();</span><br> |
| * out.println("mean before adding a value is NaN = " + <span style="font-weight: bold;">stat.getResult()</span>);<br> |
| * for (int i = 0; i < values.length; i++) {<br> |
| * <span style="font-weight: bold;">stat.increment(values[i]);</span><br> |
| * out.println("current mean = " + <span style="font-weight: bold;">stat2.getResult()</span>);<br> |
| * }<br> |
| * <span style="font-weight: bold;"> stat.clear();</span><br> |
| * out.println("mean after clear is NaN = " + <span style="font-weight: bold;">stat.getResult()</span>); |
