VAR model Diagnostics

[Alvin]

Good day,

I am conducting an estimation of the local projection (LP) method in EViews. Before I can do that, I have to estimate a VAR model. I want to ensure that the model I am using for the LP estimation is diagnostically sound. Is there a technique one can use to get the model to be normal, homoskedastic, and free of autocorrelation?

Thanks
