Helper functions to compute important statistics from correlation coefficients.
r2z(r) z2r(z) r2t(r, n) r2p(r, n) rconfint(r, n, alpha = 0.05) compcorr(r1, r2, n1, n2)
r, r1, r2 |
a correlation value |
z |
a Z-score |
n, n1, n2 |
sample sizes |
alpha |
the significance level to use |
r2z()
: converts correlation coefficients to z-scores
z2r()
: converts z-scores to correlation coefficients
r2t()
: Converts correlation coefficients to t-scores
r2p()
: Computes the two-sided p-value for a given correlation
rconfint()
: Computes confidence intervals for a given correlation coefficient
compcorr()
: computes the significance of the difference between two correlation coefficients
cormean, multiple.cor, partial.cor
z <- r2z(.5) r <- z2r(z) t<-r2t(r,30) r2p(r,30) print(rconfint(r,30)) print(compcorr(.5,.7,20,20))
