[BUG] Vector.cov does not return correct covariance #83

Closed bvenn closed 4 years ago

bvenn commented 4 years ago

Describe the bug Vector.cov reports an incorrect value as covariance of two samples. The same is true for Vector.covPopulation.

To Reproduce Vector.covPopulation (vector [5.;12.;18.;23.;45.;]) (vector [2.;8.;18.;20.;28.;])

Fix The loop exit happens too early (by one increment).
