Transform Fischer's Z into the scale of a correlation coefficient
Description
A function to transform Fischer's Z^\prime into the scale of a correlation coefficient.
Usage
transform_Z.r(Z)
Arguments
Z
Value of Fisher's Z^\prime (also called Fisher's Z).
Details
This function is typically used in the context of forming a confidence interval for a population correlation coefficient. Note that, in that situation, the two variables are assumed to follow a bivariate normal distribution (e.g., Hays, 1994).
Value
returns a value on the scale of a correlation coefficieint from a value of Fisher's Z.
