WebThe default arguments correspond to the standard bivariate normal distribution with correlation parameter \rho = 0 ρ =0 . That is, two independent standard normal distributions. Let sd1 (say) be sqrt (var1) and written \sigma_1 σ1, etc. Then the general formula for the correlation coefficient is \rho = cov / (\sigma_1 \sigma_2) ρ = cov ...
