Really I do not understand what you want to do especially when the
ticket contains some very basic errors. Can you please provide a
couple of real examples with expected output that clearly show what
>From a statistical viewpoint, np.cov is correct because it outputs the
variance/covariance matrix. Also I believe that changing the np.cov
function will cause major havoc because numpy and people's code depend
on the current behavior.
