In the example here one can conclude that PRICE does not Granger cause
QNC. Gretl then gives the results of all bivariate Granger Causality
tests. There are other possible Granger Causality tests. If one
divides the n dimensional VAR into two sub-systems of dimension n1 and
n2 one may ask if the first system Granger causes the second. In the
example one may ask if PRICE Granger causes QNC and INCOME. This is a
joint test on the lags of PRICE in the QNC and INCOME equations. AS
far as I know this can not be implemented within the VAR estimation in
the GUI. (I presume that the test can be implemented using the
simultaneous equations estimation routines). Would it be possible
or worthwhile to add these items to the test menu in the Vector
autoregression results window.
