The Kalman filter is a recursive estimator. This means that only the estimated state from the previous time step and the current measurement are needed to compute the estimate for the current state. In contrast to batch estimation techniques, no history of observations and/or estimates is required. In what follows, the notation represents the estimate of at time n given observations up to and including at time m ≤ n. WebKalman Filters are used in signal processing to estimate the underlying state of a process. They are incredibly useful for finance, as we are constantly taking noisy estimates of key …
