Use Fixed-Interval Smoothing on Time Series
Performs fixed-interval smoothing on a univariate time series via a state-space model. Fixed-interval smoothing gives the best estimate of the state at each time point based on the whole observed series.

- possible arguments for future methods.
A time series, with as many dimensions as the state space and results
at each time point of the original series. (For seasonal models, only
the current seasonal component is returned.)
