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 … In statistics, the Fisher transformation (or Fisher z-transformation) of a Pearson correlation coefficient is its inverse hyperbolic tangent (artanh). When the sample correlation coefficient r is near 1 or -1, its distribution is highly skewed, which makes it difficult to estimate confidence intervals and apply tests of significance for the population correlation coefficient ρ. green house sheathing
