WebMar 31, 2024 · The following transformation functions are currently implemented: transf.rtoz: Fisher's r-to-z transformation for correlation coefficients (same as atanh (x) ). transf.ztor: inverse of Fisher's r-to-z transformation (i.e., the z-to-r transformation; same as tanh (x) ). transf.logit: logit (log odds) transformation for proportions (same as ... Webinverse hyperbolic tangent, or atanh, of r is much better behaved. This transform, within statistics often labeled Fisher’s z, is said to be normally distributed to a good approximation. The basic tactic is now evident: apply standard normal-based technique on the z scale, and then back-transform using its inverse transform, the hyperbolic ...
