Vector autoregression (VAR) estimation is a vital tool in economic studies. VARs, however, can be dimensionally cumbersome and overparameterized. The vgets command allows for a general-to-specific estimation of VARs— overcoming the potential overparameterization—and provides tests for Granger causality, estimates of the long-run effects, and the cumulative impulse–response of each variable in the system; it also offers diagnostics that facilitate a genuinecausality interpretation of the Granger causality tests.

vgets：用于估算一般特定VAR，Granger因果关系，稳态影响和累积冲激响应的命令

向量自回归（VAR）估计是经济研究中的重要工具。但是，VAR可能在尺寸上很繁琐且参数过大。所述vgets命令允许VARs-的克服潜在的一般到特殊估计overparameterization-和Granger因果提供测试，的长期影响，并且该系统中每个变量的累积脉冲响应估计; 它还提供了诊断方法，有助于对Granger因果关系检验进行真正的因果关系解释。
