What is VAR lag order selection criteria?

The six criteria are the Schwarz Information Criterion (SIC), the Hannan-Quinn Criterion (HQC), the Akaike Information Criterion (AIC), the general-to-specific sequential Likelihood Ratio test (LR), a small-sample correction to that test (SLR) proposed by Sims (1980), and the specific-to-general sequential Portmanteau ...

How do I choose lag length in VAR?

In general lag length in VAR models is selected using statistical information criteria. This means that VAR models are fitted for various lengths an certain statistic is calculated. The lag length is taken to be of model with the smallest statistic.

What is lag order in VAR model?

A lag is the value of a variable in a previous time period. So in general a pth-order VAR refers to a VAR model which includes lags for the last p time periods. A pth-order VAR is denoted "VAR(p)" and sometimes called "a VAR with p lags".

How do you select lag length in cointegration?

Usually, beginners in time series econometrics tend to skip step d. e. For the cointegration, the lag length is the lag length chosen from step d minus one (since we are running the model in first difference now, unlike in level when we used VAR to decide the lag length).
