The linear regression model using matrices

SpletThis notebook describes how to extend the statsmodels statespace classes to create and estimate a custom model. Here we develop a local linear trend model. The Local Linear Trend model has the form (see Durbin and Koopman 2012, Chapter 3.2 for all notation and details): y t = μ t + ε t ε t ∼ N ( 0, σ ε 2) μ t + 1 = μ t + ν t + ξ t ξ ...
