"Webedit in response to @pbneau's comments: my suspicion was that the tetrachoic and phi coefficients would diverge in the limit cases: as ρ → 0 and as the cutoffs for the latent rating move away from the mean ratings. I tested this with my own code (in Matlab) for tetrachoric and phi coefficient. " - Phi correlation matrix in r
