Fisher's r to z' transformation - help needed
...formation of the Pearson's r but the
standard error does not appear to be correct. I have simulated an example
using the R code below. The z' data appears to have a reasonably normal
distribution but the standard error given by the formula 1/sqrt(N-3) (from
http://davidmlane.com/hyperstat/A98696.html) gives a different results than
sd(z). Can anyone tell me where I am going wrong?
