Dear Frank and Felipe,
Thank you both for your replies. The code looks exactly like the
formula in Japanese wikipedia which I was trying to make sense of (as it
wasn't in English wikipedia). Thank you for sharing your code with, Felipe!
And the clarification, Frank. Knowing many ways of
Hi all,
I am trying to figure out the formula used by R's Spearman rho (using
cor(method=spearman)) because I can't seem to get the same value as by
calculating by hand. Perhaps I'm using cor wrong, but I don't know
where. Basically, I am running these commands:
Hi,

Hi,
You can try with
cor.test(rank(y[1]),rank(y[2]))
Thanks for this! It didn't solve my problem, but it helped me realize
that the formula I was using by hand is invalid for the tie case. I
just realized that with R's cor function, the Pearson correlation

This should be kept in mind when assessing the ``instability''

I have a question regarding normality testing with the nortest

suited a newsgroup such as sci.math. However, just in case it is
implemented differently, I was hoping someone who has used it can help me
