Correlation tools

Description

Helper functions to compute important statistics from correlation coefficients.

Usage

r2z(r)

z2r(z)

r2t(r, n)

t2r(t, n)

r2p(r, n)

rconfint(r, n, alpha = 0.05)

compcorr(r1, r2, n1, n2)

## S3 method for class 'compcorr'
print(x, ...)

Arguments

r, r1, r2	a correlation value
z	a Z-score
n, n1, n2	sample sizes
t	a t-score
alpha	the significance level to use
x	a compcorr object to print
...	ignored

Functions

• r2z(): converts correlation coefficients to z-scores

• z2r(): converts z-scores to correlation coefficients

• r2t(): Converts correlation coefficients to t-scores

• t2r(): Converts t-scores to correlation coefficients

• r2p(): Computes the two-sided p-value for a given correlation

• rconfint(): Computes confidence intervals for one or multiple correlation coefficients

• compcorr(): computes the significance of the difference between two correlation coefficients

• print(compcorr): computes the significance of the difference between two correlation coefficients

Examples

z <- r2z(.5)
r <- z2r(z)
t<-r2t(r,30)
r2p(r,30)
print(rconfint(r,30))
print(compcorr(.5,.7,20,20))
