Let's assume you have variables X1, x2, x3, etc. and you wish to create a new variable cond with values like 1, 2, 3, etc. then do one of these:
if( x1 = 1 or x2 = 3) cond = 1. if( (x2 = 1 and x4=1) or x3 = 1) cond = 2. etc.... execute. OR, do this: do if( x1 = 1 or x2 = 3). compute cond = 1. else if( (x2 = 1 and x4=1) or x3 = 1). compute cond = 2. else. compute cond = -1. end if. execute. The main difference is that the second method assures that cond is assigned something. But unassigned values will be system missing, so maybe that's better. If you had a single variable that you wanted to create a new variable with grouped values, then RECODE would be easier but AFAIK it only works on values from a single variable. -Alan On 10/23/2017 3:37 PM, Betsabé Cohen wrote: > Hi john and Alan > I’d like to create a new variable where, given certain codes in > certain variables you get other codes in the new variable: if > respondent answer code 1 un variables 5,6 or 7 so in the new variable > it should be code 1, if respondent gets code 1 in variable 8 it should > be code 2 in the new variable but if respondent gets code 2 it should > be code 3 in the new variable. > I wonder sintaxis should be condtional if do, but i dont know... > > El El lun, 23 oct. 2017 a las 14:03, Alan Mead <am...@alanmead.org > <mailto:am...@alanmead.org>> escribió: > > And if John's explanation is insufficient, please explain what you > are trying to do.
