WebAfer perusing the documentation for KFAS, it seems to me that KFS() will return what you want in components V_eta and V_eps of the object you name out. (This is the case because you are dealing with a univariate time series, so the only diagonal term of V_eps is the variance you want.). You should expect about the same values from your code and any … WebMay 15, 2024 · Thanks for contributing an answer to Stack Overflow!

WebFunction fitSSM finds the maximum likelihood estimates for unknown parameters of an arbitary state space model, given the user-defined model updating function.
WebState space modelling is an efficient and flexible framework for statistical inference of a broad class of time series and other data. KFAS includes computationally efficient functions for Kalman filtering, smoothing, forecasting, and simulation of multivariate exponential family state space models, with observations from Gaussian, Poisson, binomial, negative … WebDefinition of fissm in the Definitions.net dictionary.
