Web22. The decision to include a lagged dependent variable in your model is really a theoretical question. It makes sense to include a lagged DV if you expect that the current level of the DV is heavily determined by its past level. In that case, not including the lagged DV will lead to omitted variable bias and your results might be unreliable. WebTwo conditions must hold true for omitted-variable bias to exist in linear regression: the omitted variable must be a determinant of the dependent variable (i.e., its true regression coefficient is not zero); and. the omitted variable must be correlated with one or more of the included independent variables (i.e. cov (z,x) is not equal to zero). gps whvWebBy far the most common approach to including multiple independent variables (which are often called factors) in an experiment is the factorial design.
