Fisher_z2r: Fisher's z to r transformation.

In sjpierce/piercer: Functions for Research and Statistical Computing

Fisher's z to r transformation.

Description

This function uses Fisher's z to r transformation to convert a z-score into a correlation.

Usage

Fisher_z2r(z)

Arguments

z	A numeric value (or vector) for the z-score(s).

Details

=============================================================================

This function uses Fisher's z to r transformation to convert a correlation into a z-score. Missing values of z result in NA values. This is also called the hyperbolic tangent transformation (tanh), so this is a wrapper for the base::tanh() function.

Value

A numeric value (or vector) for the correlation coefficient(s).

References

To be added later.
