When i was estimation a simultaneous equation model, a error massage
appeared: You must include a constant in this sort of model.
Could anybody be kindly tell me the reason and how to solve the problem?
Thanks!
PS. system setting:
# set the model up as a system
system name="all"
equation pf 0 gdp
Hi,
Is there any command in gretl to obtained grouped descriptive statistics
based on a dummy or a discrete variable (without passing through "smpl
--restrict" command) ?
best,

Follow-up in regard to Jack's nice presentation of the delta

This is not documented yet (nor finalized, if people have good

for the "restrict" command:
restrict
rfunc =
end restrict
