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 ... SpletEssentially, regression is the “best guess” at using a set of data to make some kind of prediction. It’s fitting a set of points to a graph. There’s a whole host of tools that can run regression for you, including Excel, which I used here to …

The Local Linear … SpletWe will consider the linear regression model in matrix form. For simple linear regression, meaning one predictor, the model is Yi = β0 + β1 xi + εi for i = 1, 2, 3, …, n This model … SpletIn statistics, ordinary least squares (OLS) is a type of linear least squares method for choosing the unknown parameters in a linear regression model (with fixed level-one effects of a linear function of a set of explanatory variables) by the principle of least squares: minimizing the sum of the squares of the differences between the observed dependent … how to spell well known
