This code should work with any other options you choose (see help metan):
metan r lower upper
or
metan r lower upper, weight(n)

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.
