For lower bound lower and upper bound upper , the mean is 0.5 * (lower + upper) .

Usage

From source file:org.apache.solr.client.solrj.io.stream.eval.UniformDistributionEvaluatorTest.java

@Test
public void test() throws IOException {

    values.clear();/*from w  ww.j  a v a 2 s .  c  o  m*/
    values.put("l1", 3);
    values.put("l2", 7);

    UniformRealDistribution dist = new UniformRealDistribution(3, 7);
    Assert.assertEquals(dist.getNumericalMean(),
            ((UniformRealDistribution) factory.constructEvaluator("unif(l1,l2)").evaluate(new Tuple(values)))
                    .getNumericalMean());
}
