| Generic univariate summary statistic objects. |
| |
| <h3>UnivariateStatistic API Usage Examples:</h3> |
| <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/> System.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/> |
| System.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/> |
| System.out.println("current mean = " + <span style="font-weight: bold;"> |
| stat2.getResult()</span>);<br/> }<br/> <span style="font-weight: bold;"> |
| stat.clear();</span><br/> System.out.println("mean after clear is NaN = " |
| + <span style="font-weight: bold;">stat.getResult()</span>);</code> |
