[Gretl-devel] VARs as system special case ($sysA, $sysB, etc.)

Hi, I propose to treat VARs more fully as a special case of a structural system of equations. This would imply to make the accessors $sysA and $sysB accessible, and probably a few other things as well. If you want I could write down a complete list. $sysA is already quite easy I guess, as $compan[1:N,]. However, I don't see why users must be expected to know this trick and not directly provide the endogenous lagged coefficients. And for $sysB it's more involved. And BTW, in the built-in help the definition of $sysA is not totally clear, whether the ordering is by variable or by lags. Only the section in the user guide explains it 100%. I could imagine that such stuff need not be implemented at the C level in principle, but it's not obvious (to me) how the interface should look like to come as close to the $-accessors as possible. For VECMs the situation is maybe less clear, but given that you specify it by using the levels of the variables and that $compan also exists there, I tend to think it could be covered just as well. Opinions? thanks, sven
