Fisher's z distribution
Fisher's z-distribution is the statistical distribution of half the logarithm of an F-distribution variate: $${\displaystyle z={\frac {1}{2}}\log F}$$It was first described by Ronald Fisher in a paper delivered at the International Mathematical Congress of 1924 in Toronto. Nowadays one usually uses the F-distribution instead.

S. Gosset (the original "Student") in a letter. Gosset attempted to publish it, giving Fisher full credit, but Pearson rejected the paper. Fisher's method, as applied to the substantially similar but more difficult problem of finding the distribution of a sample correlation coefficient, was eventually ...
WebMy understanding is that the Fisher's transform is used because the r's are not normally distributed. Therefore, it seems that the transform makes sense if one is just comparing a single r-value to 0 (i.e. in lieu of testing against a t-distribution with the test statistic t = r ∗ n − 2 1 − r 2 ). However, in my t-test, I am comparing the ...
