A function to transform Fischer's Z into the scale of a correlation coefficient.
Fisher's Z or Fisher's Z\' value.
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).
returns a value on the scale of a correlation coefficieint from a value of Fisher's Z.
