Statistical power of correlations.

[Collin Lynch]

My apologies for the statistical naivete of my question but...

Is there an established method or calulating the statistical power of a
correlation test?  And if so is there a method in R for it?

        Thank you,
        Collin Lynch.

There's a pwr.r.test in the "pwr" package. This is based on the Z transform, which makes quite good sense to me.

Hi Collin,

Look in the package 'pwr' for 'pwr.r.test'.
