WebSep 19, 2024 · As a real world example, I am currently looking at asset X valued $0.76235 and asset Y values at $0.04545. My Kalman filter quickly begins producing nearly perfect y-hat values, but results in beta of 0.0219 and intercept of 0.02874. With such a high intercept, my hedge [X * beta] is $0.016705. Clearly far lower than the Y value / y-hat value. WebParameters: smoothed (boolean) – compute Kalman smoother (used by smooth); filtered (boolean) – return (one-way) filtered data; likelihoods (boolean) – return likelihoods of each step; gains (boolean) – return Kalman gains and pairwise covariances (used by the EM algorithm).If true, the gains are provided as a member of the relevant subresult …
