SAVE Subcommand (OVERALS command)

SAVE lets you add variables containing the object scores that are computed by OVERALS to the active dataset.

  • If SAVE is not specified, object scores are not added to the active dataset.
  • A variable rootname can be specified on the SAVE subcommand, to which OVERALS adds the number of the dimension. Only one rootname can be specified, and it can contain up to six characters.
  • If a rootname is not specified, unique variable names are automatically generated. The variable names are OVE n_m, where n is a dimension number and m is a set number. If three dimensions are saved, the first set of names are OVE1_1, OVE2_1, and OVE3_1. If another OVERALS is then run, the variable names for the second set are OVE1_2, OVE2_2, OVE3_2, and so on.
  • Following the name, the number of dimensions for which you want object scores saved can be listed in parentheses. The number cannot exceed the value of the DIMENSION subcommand.
  • The prefix should be unique for each OVERALS command in the same session. Otherwise,, OVERALS replaces the prefix with DIM, OBJ, or OBSAVE. If all of these prefixes already exist, SAVE is not executed.
  • If the number of dimensions is not specified, the SAVE subcommand saves object scores for all dimensions.
  • If you replace the active dataset by specifying an asterisk (*) on a MATRIX subcommand, the SAVE subcommand is not executed.

Example

OVERALS CAR1 CAR2 CAR3(5) PRICE(10)
/SET=2(3,1)
/ANALYSIS=CAR1 TO CAR3(SNOM) PRICE(NUME)
/DIMENSIONS=3
/SAVE=DIM(2).
  • Analyzed items include three single nominal variables, CAR1, CAR2, and CAR3 (each with 5 categories) and one numeric level variable (with 10 categories).
  • The DIMENSIONS subcommand requests results for three dimensions.
  • SAVE adds the object scores from the first two dimensions to the active dataset. The names of these new variables will be DIM00001 and DIM00002, respectively.
