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!

WebHistory. The basic idea now known as the Z-transform was known to Laplace, and it was re-introduced in 1947 by W. Hurewicz and others as a way to treat sampled-data control systems used with radar. It gives a tractable way to solve linear, constant-coefficient difference equations.It was later dubbed "the z-transform" by Ragazzini and Zadeh in … WebThis transform, within statistics often labeled Fisher’s z, is said to be normally distributed to a good approximation. The basic tactic is now evident: apply standard normal-based …

WebFisher Z transformation is a method that transforms the Pearson’s correlation coefficient r to the normally distributed variable z. The Z in the Fisher Z transformation stands for the normal z -score. It is named after Fisher who developed this transformation.
