WebR fitSSM of KFAS package. Details: Note that fitSSM actually minimizes -logLik(model), so for example the Hessian matrix returned by hessian = TRUE has an opposite sign than expected. This function is simple wrapper around optim.For optimal performance in complicated problems, it is more efficient to use problem specific codes with calls to … WebPackage KFAS contains functions for Kalman filtering, smoothing and simulation of linear state space models with exact diffuse initialization. Arguments Details Note, this help page might be more readable in pdf format due to the mathematical formulas containing subscripts. The linear Gaussian state space model is given by WebI am using KFAS to fit a dynamic logistic model of the form; y ^ = β t x + ϵ β t = β t − 1 + η So the regression parameters change over time, and act as latent variables to be estimated by the filter. Can state space models of this form generally accept situations where we have multiple observations per time period? light on the yoga sutras of patanjali iyengar
