u_fisherZ {eclust} | R Documentation |
Calculate Fisher's Z transformation for correlations. This can
be used as an alternative measure of similarity. Used in the
s_generate_data
function
u_fisherZ(n0, cor0, n1, cor1)
fisherTransform(n_1, r1, n_2, r2)
n0 |
number of unexposed subjects |
cor0 |
correlation matrix of unexposed covariate values. Should be dimension pxp |
n1 |
number of exposed subjects |
cor1 |
correlation matrix of exposed covariate values. Should be dimension pxp |
n_1 |
number of unexposed subjects |
r1 |
correlation for unexposed |
n_2 |
number of exposed subjects |
r2 |
correlation for exposed |
a pxp matrix of Fisher's Z transformation of correlations
fisherTransform
is called internally by u_fisherZ
function
