Webdfms is intended to provide a simple, numerically robust, and computationally efficient baseline implementation of (linear Gaussian) Dynamic Factor Models for R, allowing straightforward application to various contexts such as time series dimensionality … WebThe MARSS model The MARSS model includes a process model and an observation model. The process component of a MARSS model is a multivariate first-order autore-gressive (MAR-1) process. The multivariate process model takes the form xt = Bxt 1 +u +wt; wt ˘MVN(0,Q) (1) The x is an m 1 vector of state values, equally spaced in time, and B, u and ...
