Thanks a lot.
When testing if the residuals of ARIMA is autocorrelated,
degree of freedom of Ljung-Box Q stat. is just the number of lag, or the
number of lag minus the number of parameter in gretl?
Thanks a lot.

Dear all:
I am confused about that degree of freedom is the number of lag or the nuber of
lag minus the number of parameter estimated
(When using Ljung-Box Q stat. to test if the residuals of ARIMA is

It seems that degree of freedom of the nuber of lag minus the number of
The degrees of freedom of the asymptotic distribution of the
Ljung-Box test statistic is the number of auto correlations included
minus the number of parameters estimates. You will find an
explanation in any good time series test (e.g. Brockwell and Davis
(2006), Shumway and Stoffer (2006 2011(?

Gretl provides the Ljung-Box statistic, wich is a refinement of
Box-Pierce Q with better small sample properties. You may se

Does it provide Box-Pierce Q statistic to test if residual is autocorrelation

Thanks a lot
