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.
