R help - Oct 2006 - Spearman correlation test confidence intervals

Hello,

How does one calculate the confidence levels for a spearman correlation
test?  I noticed cor.test(x,y) gives the confidence levels only for
pearson test.

Thank you for the suggestions, in advance.

Best Regards,

Mahesh Krishnan

You can't. Not easily anyway. The distribution of the Spearman
correlation is known under the null hypothesis of independence
(through symmetry considerations), but not otherwise. In largish
samples, I suppose that resampling techniques could be employed.
