WebAug 15, 2006 · The coefficients are converted using Fisher's z-transformation with standard errors (N − 3) −1/2. The two transformed values are then compared using a standard normal procedure. When data are not bivariate normal, Spearman's correlation coefficient rho is often used as the index of correlation. 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). WebI have understood that I can use Fisher's z-transform to calculate this by z o b s = n − 3 2 ln ( 1 + r 1 − r) and finding the p-value by p = 2 P ( Z > z o b s) using the standard normal distribution.
