Hi, I have looked into this issue, and imo the test tolerance is too stringent: >> MeanTest >> testWeightedConsistency : >> java.lang.AssertionError >> java.lang.AssertionError: expected:<-5.261475053036868E-4> but >> was:<-5.26147505303894E-4> The tests compares the two computed means with a relative error of 10-14, which can lead to an quite small absolute error in case the randomized test values are distributed in an unfortunate way. In the failing example, the mean is calculated to be -5.261e-4 which leads to an absolute error of 10-18 while the two means are equal up to 10-15. The bug report is very similar: the expected mean is ~2.2e-3 and the values are equal up to 10-15.
