compCorr {maigesPack} | R Documentation |
This function takes two correlation values (or matrices of correlation values) and calculate the differences between these values (term by term) and their respective p-values by a Fisher's Z transformation.
compCorr(n1, r1, n2, r2)
n1 |
numerical or matrix of sample sizes for group 1. |
r1 |
numerical or matrix of correlation values for group 1. |
n2 |
numerical or matrix of sample sizes for group 2. |
r2 |
numerical or matrix of correlation values for group 2. |
This function use Fisher's Z transformation from scripts adapted from
the Internet:

The result of this function is a list with two numerical items.
diff |
matrix (or a single number) of differences between correlation values from two groups |
pval |
matrix (or a single number) of p-values of differences between the correlation values |
