Matrix Input (FACTOR command)

  • FACTOR can read matrix materials written either by a previous FACTOR procedure or by a procedure that writes correlation or covariance matrices. See the topic Universals for more information.
  • MATRIX=IN cannot be used unless a active dataset has already been defined. To read an existing matrix data file at the beginning of a session, first use GET to retrieve the matrix file and then specify IN(COR=*), IN(COV=*) or IN(FAC=*) on MATRIX.
  • The VARIABLES subcommand cannot be used with matrix input.
  • For correlation and covariance matrix input, the ANALYSIS subcommand can specify a subset of the variables in the matrix. You cannot specify a subset of variables for factor-loading matrix input. By default, the ANALYSIS subcommand uses all variables in the matrix.
