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. WebJan 2, 2016 · z.transform implements Fisher's (1921) first-order and Hotelling's (1953) second-order transformations to stabilize the distribution of the correlation coefficient. After the transformation the data follows approximately a normal distribution with constant variance (i.e. independent of the mean). WebDec 11, 2013 · compare_correlation _coefficients.
