Kendall package tau-a, b, and c
2 messages · Kota Hattori, Rui Barradas
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 Em 20-08-2012 03:16, Kota Hattori escreveu:
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. http://stackoverflow.com/questions/2557863/measures-of-association-in-r- kendalls-tau-b-and-tau-c Yours, Kota This email may be confidential and subject to legal privilege, it may not reflect the views of the University of Canterbury, and it is not guaranteed to be virus free.
