Fisher's z transformation

WebMar 10, 2024 · Is there any way to get the sampling variance of correlation given Fisher's z and its variance? To make it more clear: suppose z = 0.5493 and var(z) = 0.0103. Transforming z to r will give us r = 0.55. Now, what I need is var(r). Thank you! 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: …
