Abstract: The mean group (MG) estimators are proposed to estimate multilevel (vector) autoregressive models with intensive longitudinal data. The MG estimator was originally proposed in econometrics but is new to the behavioural science literature. Since the naive MG estimator suffers from the small sample bias problem, jackknife and analytical bias corrections are proposed. It is argued that the MG estimator has several advantages over existing methods, such as restricted maximum likelihood or Bayesian methods in model specification and implementation. Monte Carlo simulation is performed to investigate the performance of the MG estimators and compare them with the existing methods. The simulation results indicate that the bias-corrected MG estimators perform superior or comparable to the existing methods.
