 public void testVarianceScalar() {
   assertThat(
       Stats.variance(set, mean), equalTo(1.2)); // more accurate than Stats.varianceVector()
 }

Example #2

File: StatsTest.java Project: Afromee/cilib

 @Test(expected = IllegalArgumentException.class)
 public void testEmptySetForVarianceScalar() {
   Stats.variance(new ArrayList<Pattern>(), mean);
 }
