The Granger causality test is one of the steps to model a VAR. It is used to order the variables in the VAR model, however, what happens when the test is inconclusive (not conclusive because it gives negative chi values).
Can I continue with the VAR modeling?
Or is it better to exclude that variable (the one who give me the negative values)?
