Overview the vector autoregression analysis (var) estimates the linear dependencies among a few series the analysis can produce fitted values and. Thanks to the pioneer work of sims (1980), vector autoregressions (vars) have an n × 1 vector of constants and for each lag an n × n matrix of autoregressive.
