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. WebSo a linear regression equation should be changed from: Y = β 0 + β 1 X 1 + β 2 X 2 + ε. to: Y = β 0 + β 1 X 1 + β 2 X 2 + β3X1X2 + ε. And if the interaction term is statistically significant (associated with a p-value < 0.05), then: β 3 can be interpreted as the increase in effectiveness of X 1 for each 1 unit increase in X 2 (and ...
