Re: st: meta-analysis with correlation coefficients

[John Antonakis <john.antonakis@unil.ch>]

Hi Jonathan:

I thanked you too soon.

Quick question:

Suppose my first r is .321 for an n of 53. The  the SE of r is 
.14142136. The atanh (r to z' transformation) of r is 0.332762; thus, 
the CI is 0.60994745 to 0.05557572. The tanh of this (reverse the r to 
z' transformation) is 0.544090107 to 0.055518572. Nick's program gives 
the same thing:

. corrcii 53 0.321,

      n       r      95% confidence limits
     53      0.321      0.056     0.544

OK, this is all easy. However, which numbers do I input for -metan-, 
specifically?

TIA,
John.
