[Gretl-users] IV: instruments only for specific variables

Hello, I am trying to replicate Verbeek's schooling example (Ch. 5.3). He does an IV estimation for a wage equation (p. 150, table 5.3) with 7 regressors (incl. the constant) but instruments only 3 variables and hence only uses three instruments. In stata one can associate instruments to specific variables like: ivreg lwage76 (ed76 exp76 exp762 = age76 age762 nearc4) black smsa76 south76 where only "ed76 exp76 exp762" are "instrumented". Is this possible in gretl? I did not find any hints... Cheers, Artur
