If the drop down is being populated BY arbitrarily-added tags, then it probably makes some sense, and in that case the drop-down should mimic selection order. Many selection-order statistics have been developed to assist researchers in fitting a VAR of the correct order. Several of these selection-order statistics appear in the[TS] var output. The varsoc command computes these statistics over a range of lags pwhile maintaining a common sample and option specification. Lütkepohl H.

QUESTIONS: How should I choose the best model? How can I compare the goodness of fit of VAR model with different order? How can I validate the model?

When clicked on ‘lag-order selection statistics’, a varsoc window will open in STATA as shown in figure 2. In the varsoc window, select two components on the main page: the list of dependent variables (GDP and PFC), and the maximum lag order. Here the maximum lag order refers to the maximum lag you want to check for the results.

From such a model you will not be able to obtain impulse response functions, while variance decomposition will be trivial (none of the variables explains the variance). The selection of zero lag suggests that VAR might not be a good model for your data, so you might want to explore alternative models. statsmodels.tsa.vector_ar.var_model.VAR.fit¶ VAR. fit (maxlags = None, method = 'ols', ic = None, trend = 'c', verbose = False) [source] ¶ Fit the VAR model. Parameters maxlags {int, None}, default None. Maximum number of lags to check for order selection, defaults to 12 * (nobs/100.)**(1./4), see select_order function.
