This is not a "devel" question. Please post this sort of thing
to the gretl-users list. But this time...
Here is what I'm writting at the system of simultaneous equations
window
equation y1 const x1 x2 x3
equation y2 const x1 x2 x3
equation y3 const x1 x2 x3
b[1,3] - b[2,2] = 0
b[1,4] - b[3,2] = 0
b[2,4] - b[3,3] = 0
... and so on.
after choosing the appropriate estimator method and
"enter," gretl returns
the following message: "Syntax error in command line"
Please could you help me to understand what am I doing wrong?
You're trying to combine two commands in one. You need to
define your system first, then restrict it. A line such as
b[1,3] - b[2,2] = 0
is valid in a restriction block, but not in the block that
defines a system.
Once you have defined and estimated the system (unrestricted),
you get a chance to impose restrictions (under the Tests menu
in the window that displays the system results).
