WebRonald Fisher. Fisher's z-distribution is the statistical distribution of half the logarithm of an F -distribution variate : It was first described by Ronald Fisher in a paper delivered at the International Mathematical Congress of 1924 in Toronto. [1] Nowadays one usually uses the F -distribution instead.
