Gauss-Markov Model 4.1 Model Assumptions So far we've approached the linear model only as a method of mathematical approximation. In this chapter, we pose the Gauss-Markov model which embodies the most common assumptions for the statistical approach to the linear model, leading to the Gauss-Markov Theorem. The Gauss … WebFeb 27, 2024 · When extending the state space modelling to non-linear or non-Gaussian models, some diﬃculties arise. As the model densities are no longer analytically tractable, computing the latent state distributions, as well as hyperparameter estimation of the model becomes more diﬃcult.
