ANALYSIS Subcommand (FACTOR command)

The ANALYSIS subcommand specifies a subset of the variables named on VARIABLES for use in an analysis.

  • The specification on ANALYSIS is a list of variables, all of which must have been named on the VARIABLES subcommand. For matrix input, ANALYSIS can specify a subset of the variables in a correlation or covariance matrix.
  • Only one ANALYSIS subcommand is allowed. When multiple ANALYSIS subcommands are specified, the last is in effect.
  • If no ANALYSIS is specified, all variables named on the VARIABLES subcommand (or included in the matrix input file) are used.
  • Keyword TO in a variable list on ANALYSIS refers to the order in which variables are named on the VARIABLES subcommand, not to their order in the active dataset.
  • Keyword ALL refers to all variables named on the VARIABLES subcommand.

Example

FACTOR VARIABLES=V1 V2 V3 V4 V5 V6
   /ANALYSIS=V4 TO V6.
  • This example requests a factor analysis of V4, V5, and V6. Keyword TO on ANALYSIS refers to the order of variables on VARIABLES, not the order in the active dataset.
  • Cases with missing values for all variables specified on VARIABLES are omitted from the analysis. (The default setting for MISSING.)
  • By default, the CORRELATION method is used and a principal components analysis with a varimax rotation is performed.
