compCorr(n1, r1, n2, r2)

Arguments

n1

n for correlation 1.
r1

r for correlation 1.
n2

n for correlation 2.
r2

r for correlation 2.

Value

list containing diff(Z1, Z2) and pval for difference.

Details

Test whether two correlation coefficients are statistically different using the difference between Fisher's Z transforms.
