WebMay 24, 2024 · 1. I'm having a list of Pearson's correlation coefficients (r). Then, I performed the Fisher's Z transformation using the formula: z = 1/2 ln (1+r/1-r). Now, I want to compute corresponding p-values for each identified z score. After referring to Google, I detect a formula to compute p-value (two-sided) like: p-value = 2*pnorm (-abs (z)) Is it ...

WebFisher Transformation. Definition 1: For any r define the Fisher transformation of r as follows: Property 1: If x and y have a joint bivariate normal distribution or n is sufficiently large, then the Fisher transformation r’ of the correlation coefficient r for samples of size n has a normal distribution with mean ρ′ and standard deviation ... 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!
