transform_r.Z: Transform a correlation coefficient (r) into the scale of Fischer's Z
Description
This function transform a correlation coefficient into the scale of Fischer's Z.
Usage
transform_r.Z(r)
Arguments
r
correlation coefficient (between two variables)
Value
returns a value on the scale of Fisher's Z, also called Fisher's emphZ\', from a given correlation value.
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).
