Dear GRETLer's ! I have currently a problem using genr, here is a bit of gretl reply on a script:
====================================================== gretl version 1.8.7 Current session: 2010-05-18 15:52 ? genr AAch_75-89 = Ach_75_81 + Ach_82_89 No formula supplied in genr Error executing script: halting > genr AAch_75-89 = Ach_75_81 + Ach_82_89 ====================================================== I dont see what is wrong with it, really. It seems that gretl cant create my variable that is the sum of two dummies created from a 10 modalities discrete variable. May be there is a space problem ? advice welcome on this problem ! see ya cheers Franck
