Fisher z-transformed

WebThe sampling distribution of Pearson's r is not normally distributed. Fisher developed a transformation now called "Fisher's z-transformation" that converts Pearson's r to the … WebSep 26, 2016 · The Fisher Z transform can be calculated in terms of a Pearson r as either: Z = 0.5*log((1+r)/(1-r)) or Z = atanh(r), where the latter is the inverse of the hyperbolic tangent function. They should both give similar results up to a large number of decimal places even for a high correlation.
