Need help on ordering options in VAR model

[Fiza Qureshi]

Hello, I have two questions.
1. What ordering options are available other than Cholesky Decomposition ordering in VAR (Vector autoregressive) Model? I try to run IRF (Impulse response function) using alternative ordering options but I can not find any option in STATA. I want to know different types of ordering in VAR model.
2. Why ordering of variables is important in VAR model? If you know any reference or material related to this question, please share.

1. I think this Stata blog post might help.

2. I'd watch the first half of this video. He goes into detail as to why ordering matters.

Hope this helps.
