For how to find the source code, see the help desk article in the
October 2006 R news newsletter
(http://cran.r-project.org/doc/Rnews/Rnews_2006-4.pdf) which was the
predacessor of the R journal.
Have you looked at the variance of your jitters as well? that is what
would make me more nervous (wid
Thank you for your response. The first part of my question was meant to
ask "how do I actually find the source code?" I tried to find that,
without success.
As for my comfort with a method that gives variable answers, I've
experimented by running 100 cases and take the average. When I've do
You could run the cor function on a small dataset where you know the
values of tau-a and/or tau-b (either because you hand computed them,
or found an example on the internet showing the difference), that
would give some good evidence as to which is used.
Or you could look at the source code, R is
How can I find out whether the cor function with method="Kendall"
computes Kendall's tau-a or tau-b. I understand that tau-b deals better
with ties, and I'm wanting to look for correlation in two variables that
have lots of ties (especially lots of zeroes for one of them). The
