        I am confused as to the contradicting theories put across in the notes. At one place it says ‘Using a Lagged Dependent Variable as an Independent Variable’ leads to model misspecification.

        On the other hand AR models use a lagged dependent variable as an independent variable.

        What’s the logic behind using either?

          My understanding is that AR models are for time series data, whereas model msipecification arises from use of a lagged dependent variable as an independent variable in normal cross sectional regression.

            Oh ok. That might make sense since they were from two different chapters.
