Example of a CLPA with 4 time points and 2 variables, x and y. Simplified, without assuming a mean structure or latent equivalents to the manifest variables, other parameters include exogenous variances (phi), correlations at the same time point across exogenous variables (r) or via the disturbances (psi), cross-lagged paths (b1 to b6), autoregressive paths (b7 to b12), and endogenous residuals (zeta).
