/**
*
* Generic univariate summary statistic objects.
*
* UnivariateStatistic API Usage Examples:
*
* UnivariateStatistic:
* /∗ evaluation approach ∗/
* double[] values = new double[] { 1, 2, 3, 4, 5 };
* UnivariateStatistic stat = new Mean();
* out.println("mean = " + stat.evaluate(values));
*
*
* StorelessUnivariateStatistic:
* /∗ incremental approach ∗/
* double[] values = new double[] { 1, 2, 3, 4, 5 };
* StorelessUnivariateStatistic stat = new Mean();
* out.println("mean before adding a value is NaN = " + stat.getResult());
* for (int i = 0; i < values.length; i++) {
* stat.increment(values[i]);
* out.println("current mean = " + stat2.getResult());
* }
* stat.clear();
* out.println("mean after clear is NaN = " + stat.getResult());
*
