and implemented it in R:

# compare two correlation coefficients
# return difference and p-value as list(diff, pval)
# Fisher Z-transform
zf1 <- 0.5*log((1 + r1)/(1 - r1))
zf2 <- 0.5*log((1 + r2)/(1 - r2))
# difference
dz <- (zf1 - zf2)/sqrt(1/(n1 - 3) + (1/(n2 - 3)))
# p-value
pv <- 2*(1 - pnorm(abs(dz)))
return(list(diff=dz, pval=pv))
}
Would it make sense to use the resultant p-value to "normalize" the
correlation coefficients, using: corr &...
