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
