Fisher's z distribution
Did you know?
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.
