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>
