[Gretl-users] Using a generated dummy in following estimations

Hello all.. following the reference manual I generated a dummy variable for year 1992 (1992=1, 0 elsewhere) with command: genr tpD92 = (obs=1992) The dummy is created without problems and I can see it.. however when I try to use the new serie in estimations (hsk) I receive an error "Not numerical value in a calculation".. why?? Is "1" treated as integer instead of a numerical value?? If that is the case, how can I convert the dummy serie in a "normal" serie ? Up ot now I was using exogenously-loaded dummy variables, but let them beeing generated by gretl would be faster... thanks, Antonello -- Antonello Lobianco http://www.lobianco.org/antonello antonello a.t lobianco.org sip:0719206160@voip.eutelia.it
