We have the Ljung-Box Q statistic and p-value in the text window of the
correlogram command 'corrgm'.

Thanks for that Allin.
I thought I'd clarify the point regarding the autocorrelation test which was
unclear in my previous email. The sample period 1985:01 to 2009:04 is chosen
for specific reasons relating to stability and floating of the exchange
rate. If the autocorrelation test (automatic)
Hi all,
I've been using the modtest --autocorr option to test for autocorrelation in
a VAR model. I set the sample 1985 01 - 2009 04 (100 observations). The
automatic test and the manually specified LM test calculation do not yield
the same result because the former (automatic) uses observations
