Fischer z transformation
WebFisher developed a transformation now called "Fisher's z-transformation" that converts Pearson's r to the normally distributed variable z. The formula for the transformation is: z r = t a n h − 1 ( r) = 1 2 l o g ( 1 + r 1 − r) See Also cor.test Examples Run this code WebFisher Transformation Definition 1: For any r define the Fisher transformation of r as follows: Property 1: If x and y have a joint bivariate normal distribution or n is sufficiently large, then the Fisher transformation r’ of the correlation coefficient r for samples of size n has a normal distribution with mean ρ′ and standard deviation sr′ where
