Anmol updated MATH-1296:
------------------------
Description:
@Test
public void test() {
DescriptiveStatistics stats = new DescriptiveStatistics();
stats.addValue(1);
stats.addValue(2);
stats.addValue(4);
System.out.println(stats.getGeometricMean()); //prints 2
stats.addValue(0);
System.out.println(stats.getGeometricMean()); //prints 0,
expected NaN as per the documentation
}
The class in consideration is:
org.apache.commons.math3.stat.descriptive.DescriptiveStatistics
was:
@Test
public void test() {
DescriptiveStatistics stats = new DescriptiveStatistics();
stats.addValue(1);
stats.addValue(2);
stats.addValue(4);
System.out.println(stats.getGeometricMean()); //prints 2
stats.addValue(0);
System.out.println(stats.getGeometricMean()); //prints 0,
expected NaN as per the documentation
}
> DescriptiveStatistics return geometric mean as 0 when product of values is
> zero, expected to return NaN
