Nettet9.1 Static and Dynamic Models. From a time series analysis perspective, a general distinction can be made between “static” and “dynamic” regression models: A static regression model includes just contemporary relations between the explanatory variables (independent variables) and the response (dependent variable). This model could be … NettetAbstract Linear regression models with stationary errors are well studied but the non-stationary assumption is more realistic in practice. ... Element-wise confidence intervals for regression coefficients are constructed. The finite sample performance of our method is assessed by simulation and real data analysis.

The difference is distributional assumptions on data generating process ( x t, y t), t = 1, 2, ⋯ . In a usual regression model. ( x t, y t) is stationary. For cointegration, x t and y t are both non-stationary but the linear combination y t − β x t is. These two settings are very different ... sainsburys worksop cafe
