Nettet27. sep. 2024 · Vector Auto Regression (VAR) is a popular model for multivariate time series analysis that describes the relationships between variables based on their past values and the values of other variables. VAR models can be used for forecasting and making predictions about the future values of the variables in the system. NettetA standard regression model Y Y = β β + βx β x + ϵ ϵ has no time component. Differently, a time series regression model includes a time dimension and can be written, in a simple and general formulation, using just one explanatory variable, as follows: yt =β0 +β1xt +ϵt y t = β 0 + β 1 x t + ϵ t
