Derivation of the Method of Moments Estimators for an AR(1) Model with a Constant Term
Students often confuse population moments (theoretical values from the model's distribution) with sample moments (calculated directly from data). Another common pitfall is the correct handling of limits and denominators ( vs. ) when defining sample autocovariances, which can impact estimator bias, though MoM typically uses for direct analogy.
