WebFunction fitSSM finds the maximum likelihood estimates for unknown parameters of an arbitary state space model, given the user-defined model updating function. 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 …
