Estimating large-scale multivariate local level models with application to stochastic volatility

We derive the closed-form solution to the Riccati equation for the steady-state Kalman filter of the multivariate local linear trend model. Based on this result we propose a fast EM algorithm that provides approximated maximum likelihood estimates of the model's parameters and apply it to large-scale stochastic volatility models.
