I need to be able to create a variable that will indicate, across multiple cases that have the same ID variable value, whether a case type variable ever equaled a certain value.
So, in the example below of what i want to get, the syntax would create EverSEC and ONLYSEC, with 1=yes and 0=NO. Example ID Type EverSEC ONLYSEC 123 SEC 1 0 123 SEC 1 0 123 NSD 1 0 456 SEC 1 1 456 SEC 1 1 456 SEC 1 1 789 NSD 0 0 789 NSD 0 0 |

This approach sets a numeric variable to 1 if type is equal to SEC.
Aggregate then computes the min and max of that variable for each group of ids. MODE=ADDVARIABLES assigns the min and max of the group to each case within the group. RECODE Type ('SEC'= 1)(ELSE = 0) into TypeNUM. DATASET ACTIVATE DataSet0. AGGREGATE /OUTFILE=* MODE=ADDVARIABLES /BREAK=ID /TypeNUM_min=MIN(TypeNUM) /TypeNUM_max=MAX(TypeNUM). *initialize vars. COMPUTE EverSEC = 0. COMPUTE ONLYSEC = 0. if TypeNUM_max eq 1 EverSEC=1. if TypeNUM_max eq 1 and TypeNUM_min eq 1 ONLYSEC=1.
