WebIf you put the equation of FIsher's z transformation as expression, it can give you the z map. The expression may like this: 0.5*log((1+i1)./(1-i1)). Please see attached Figure also. 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
