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 …
