Abstract

Given a linear stochastic system of dimension n in either discrete or continuous time, the smoothing problem amounts to determining the least-squares estimates
$$\displaystyle{\hat{x}(t) =\mathop{ \mathrm{E}}\nolimits \{x(t)\mid y(s);\;t_{0} \leq s \leq t_{1}\},\quad t_{0} \leq t \leq t_{1}}$$
for some finite interval [t 0, t 1]. When t 0 → − and t 1 → , we end up in the stationary setting of Sect. 14.​3, and we shall use this fact to reduce the dimension of the smoothing algorithms.
