Hello,
I am a new user there. I'd like to know the steps in order to add
instrument variables to a single exogenous variable.
In Gretl it seems that you are able to add as many instruments as you want,
but you cannot specify the variable to which the instrument is related.
Thank you for your attention.
You don't have to. All the instruments act simultaneously on all
regressors. This is not something gretl-specific, this is the way IV
estimation works.
