... for the difference of two z-transformed Pearson correlation coefficients. ... columns 3 and 4. z1 and z2 denote Fisher's z of r1 and r2 respectively.

I did the correlation with MATLAb, but I only get 1 or -1 as result because I am correlating two values. ... Transform the sample-weighted averge fisher's z back into a sample weighted correlation.

Compute the Z-transform of exp (m+n). By default, the independent variable is n and the transformation variable is z. syms m n f = exp (m+n); ztrans (f) ans = (z*exp (m))/ (z - exp (1)) Specify the transformation variable as y. If you specify only one variable, that variable is the transformation variable. The independent variable is still n.

This transform is sometimes called the Fisher z-transform. When r is a sample Pearson correlation from a bivariate normal sample of size N and population ...

Z-Transform The Z-transform F = F(z) of the expression f = f(n) with respect to the variable n at the point z is F ( z) = ∑ n = 0 ∞ f ( n) z n. Tips If any argument is an array, then ztrans acts element-wise on all elements of the array. If the first argument contains a symbolic function, then the second argument must be a scalar.
