APPROXIMATE FILTERING OF PARAMETER DRIVEN PROCESSES
Journal of Time Series Analysis, 1982Abstract. A stationary stochastic process {θ,} is of interest but cannot be observed directly. Instead, at time t, we observe y, which is sampled from a distribution determined by the value of θt, say f(y∥θ,). A method for estimating the current value of {θ,} is described.
