WebThe 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 … An endogenous variable is a variable in a statistical model that's changed or determined by its relationship with other variables within the model. In other words, an endogenous variable is synonymous with a dependent variable, meaning it correlateswith other factors within the system being studied. … See more Endogenous variables are important in econometrics and economic modeling because they show whether a variable causes a particular effect. Economists employ causal modeling to explain outcomes by … See more In contrast to endogenous variables, exogenous variables are considered independent. In other words, one variable within the formula doesn't dictate or directly correlate to a change in another. Exogenous variables … See more For example, assume a model is examining the relationship between employee commute times and fuel consumption. As the commute time rises within the model, fuel consumption also increases. The … See more
