Hello,
I've followed your link (thanks) and in the presence of ties the value
of R's cor.test, method = "kendall", in package stats and kendall_tau_b
in the link are the same. If you have ties, cor.test will issue a
warning but that is relative to the p-value only, the reported tau,
under "sample estimates" is tau-b.
See ?cor.test
Hope this helps,
Rui Barradas

Hi all,
I would like to ask a question related to Kendall package. I ran Kendall
(x,y) and
saw the results. But I am not sure which tau values R reported. I have
ties in
my data set, so I want tau-b. Can anybody tell how Kendall package is
calculating tau values? I have looked at the package PDF, but I could
not find
any useful information. As long as I see from the following
link, there may not be any direct ways to calculate tau-b and tau-c.
