Comment(by josefpktd):

 correction: I meant kendall-tau-b for Stata (Stata reports kendall-tau-a=0
 if there is a zero variance array)

 aside: for these small examples with many ties, I'm not able to match up
 the p-values, at least not without going through all options how they can
 be calculated.)
