 To calculate Y1(t), VAR will use the past values of both Y1 as well as Y2. Likewise, to compute Y2(t), the past values of both Y1 and Y2 be used.
 
 For example, the system of equations for a VAR(1) model with two time series (variables `Y1` and `Y2`) is as follows:

 Where, Y{1,t-1} and Y{2,t-1} are the first lag of time series Y1 and Y2 respectively.
 
 The above equation is referred to as a VAR(1) model, because, each equation is of order 1, that is, it contains up to one lag of each of the predictors (Y1 and Y2).
 
 Since the Y terms in the equations are interrelated, the Y’s are considered as endogenous variables, rather than as exogenous predictors.
 
-Likewise, the second order VAR(2) model for two variables would include up to two lags for each variable (Y1 and Y2).

 Can you imagine what a second order VAR(2) model with three variables (Y1, Y2 and Y3) would look like?

 As you increase the number of time series (variables) in the model the system of equations become larger.
