示例1: testCopyConsistencyWithInitialMostElements
import org.apache.commons.math3.stat.descriptive.StorelessUnivariateStatistic; //导入方法依赖的package包/类
/**
* Verifies that copied statistics remain equal to originals when
* incremented the same way by making the copy after a majority of elements
* are incremented
*/
@Test
public void testCopyConsistencyWithInitialMostElements() {
StorelessUnivariateStatistic master =
(StorelessUnivariateStatistic) getUnivariateStatistic();
StorelessUnivariateStatistic replica = null;
// select a portion of testArray till 75 % of the length to load first
long index = FastMath.round(0.75 * testArray.length);

// Check same
Assert.assertTrue(replica.equals(master));
