Vector Autoregression - Stony Brook
Overview Vector Autoregression (VAR) model is an extension of univariate autoregression model to multivariate time series data VAR model is a multi-equation system where all the variables are treated as endogenous (dependent) There is one equation for each variable as dependent variable. In its reduced form, the right-hand side of each

REGRESSION WITH TIME SERIES VARIABLES
www.ams.sunysb.edu•Regression modelling goal is complicated when the researcher uses time series data since an explanatory variable may influence a dependent variable with a time lag. This often necessitates the inclusion of lags of the explanatory variable in the regression. •If “time” is the unit of analysis we can still regress some dependent
