With the Fourier transform, we had a complex-valued function of a purely imaginary variable, F(jω). This was something we could envision with two 2-dimensional plots (real and imaginary parts or magnitude and phase). WebJan 24, 2013 · 1 when the null hypothesis states that ρ = 0; but when the null hypothesis states that ρ = some nonzero value, we must apply Fisher’s r-to-z transformation to both r and ρ and then use the z-test shown in Eq. 5. For regression coefficients, on the other hand, the t-test shown in Eq. 8 can be used regardless of the value of b*.
