correlation-tools: 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 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
