WebNov 12, 2016 · RebeccaSalles commented on Nov 12, 2016. The latest version of the R-package "KFAS" provides a function for calculating the log-likelihood of an SSModel ("logLik.SSmodel"), however the package does not provide straightforward calculation of the Akaike's Information Criteria, namely the AIC, BIC and AICc. This would be a useful … 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 …
