Sample parallel process structural equation model. η₀ = latent intercept, η₁ = latent slope, ψ₀ = latent intercept variance, ψ₁ =slope variance, ψ_0,0;0,1, = latent covariances among factors, θ₀ = latent intercept mean, θ₁ = latent slope mean, ε_1–4 = observed score residuals, ${\sigma }_{1-4}^2=\text{residual}\text{variances}$, γ = latent variable regressions.
