R: Fisher-Transformation for Correlation to z-Score

WebFisher's Z transformation is a procedure that rescales the product-moment correlation coefficient into an interval scale that is not bounded by + 1.00. It may be used to test a null ... WebFisher's r-to-z transformation happens to be a rather effective normalizing transformation (even though this is not the primary purpose of the transformation -- see below). Many meta-analytic methods assume that the sampling variances of the observed outcomes are (at least approximately) known.
