WebThis 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 tangent, or tanh. WebOur next step was to use the Fisher Z-transform [10] (inverse hyperbolic tangent) and average the results, weighted proportionally to group size. The inverse Fisher Z-transform yielded a single ...
