WebDynamic factors. A general dynamic factor model is written as: y t = Λ f t + B x t + u t f t = A 1 f t − 1 + ⋯ + A p f t − p + η t η t ∼ N ( 0, I) u t = C 1 u t − 1 + ⋯ + C q u t − q + ε t ε t ∼ N ( 0, Σ) where y t are observed data, f t are the unobserved factors (evolving as a vector autoregression), x t are (optional ... WebJan 10, 2024 · In the previous example, we showed principal-factor solution, where the communalities (defined as 1 - Uniqueness) were estimated using the squared multiple correlation coefficients.However, if we assume that there are no unique factors, we should use the "Principal-component factors" option (keep in mind that principal-component …
WebDec 15, 2024 · The Dynamic Factor Analysis model in MARSS is x(t) = x(t-1) + w(t), where w(t) ~ MVN(0,I)y(t) = Z(t) x(t) + D(t) d(t) + v(t), where v(t) ~ MVN(0,R(t))x(1) ~ MVN(0, 5*I)Passing in form="dfa" to MARSS() invokes a helper function to create that model and creates the Z matrix for the user.
