SUBJECT Subcommand (CONJOINT command)

SUBJECT specifies an identification variable. All consecutive cases having the same value on this variable are combined to estimate the utilities.

• If SUBJECT is not specified, all data are assumed to come from one subject, and only a group summary is displayed.
• SUBJECT is followed by the name of a variable in the active dataset.
• If the same SUBJECT value appears later in the data file, it is treated as a different subject.
