Suppose we want to calculate the population correlation matrix for a mediation model with x, m, and y. We only need to specify the population path coefficients among x, m, and y in the Amatrix. flight y4168WebbThis implies that the conditional CDF may be derived directly from the copula itself. The following result is one of the most important in the theory of copulas. It essentially states that if we apply a monotonic transformation to each component in X = (X 1;:::;X d) then the copula of the resulting multivariate distribution remains the same. flight y4391

Thus, the covariance of X and Y is the expected value of the outer product of X − E(X) and Y − E(Y). Our next result is the computational formula for covariance: the expected value of the outer product of X and Y minus the outer product of the expected values.
