Simulation version of the backwards smoother
Backwards sample step from the distribution p(x_t | x_{t-1}, y_{1:t}), for use in the Gibbs Sampler This uses the joseph form of the covariance update for stability
Learn the distribution of the latent state (the smoothing distribution) p(x_{1:T} | y_{1:T}) of a fully specified DLM with observations available for all time
