If you put the equation of FIsher's z transformation as expression, it can give you the z map. The expression may like ...
WebJan 28, 2016 · With nonnormal data, the typical confidence interval of the correlation (Fisher z') may be inaccurate. The literature has been unclear as to which of several alternative methods should be used instead, and how extreme a violation of normality is needed to justify an alternative. Through Monte Carlo simulation, 11 confidence interval methods … WebFISHER's Z TRANSFORMATION. This will calculate Fisher's Z Transformation to compare correlation coefficients from different populations. HOTELLING'S t & STEIGER'S Z TESTS. Use this calculator to calculate Hotelling's t and Steiger's Z tests to compare non-nested models in the same population (i.e., for dependent correlations). ...
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!
