SAVE Subcommand (HOMALS command)

SAVE lets you add variables containing the object scores computed by HOMALS to the working data file.

  • If SAVE is not specified, object scores are not added to the working data file.
  • A variable rootname can be specified on the SAVE subcommand to which HOMALS 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 HOM n_m, where n is a dimension number and m is a set number. If three dimensions are saved, the first set of names is HOM1_1, HOM2_1, and HOM3_1. If another HOMALS is then run, the variable names for the second set are HOM1_2, HOM2_2, HOM3_2, and so on.
  • Following the rootname, the number of dimensions for which you want to save object scores can be specified in parentheses. The number cannot exceed the value on the DIMENSION subcommand.
  • If the number of dimensions is not specified, the SAVE subcommand saves object scores for all dimensions.
  • If you replace the working data file by specifying an asterisk (*) on a MATRIX subcommand, the SAVE subcommand is not executed.

Example

HOMALS CAR1 CAR2 CAR3 CAR4(5)
 /DIMENSION=3
 /SAVE=DIM(2).
  • Four variables, each with five categories, are analyzed.
  • The DIMENSION subcommand specifies that results for three dimensions will be computed.
  • SAVE adds the object scores from the first two dimensions to the working data file. The names of these new variables will be DIM00001 and DIM00002, respectively.
