PRINT Subcommand (PREFSCAL command)

The PRINT subcommand controls the display of tables. By default, PREFSCAL displays the Stress and fit values for each analysis, the coordinates of the common space, and, if applicable, the individual space weights.

  • Omitting the PRINT subcommand or specifying PRINT without keywords is equivalent to specifying COMMON and WEIGHTS.
  • If a keyword(s) is specified, only the output for that particular keyword(s) is displayed.
  • Inapplicable keywords are silently ignored. That is, a specified keyword for which no output is available—for example, the keyword INDIVIDUAL with only one source specified—will be silently ignored.

NONE. No optional output. Displays only the penalized Stress and corresponding fit values.

INPUT. Input data. Displays tables of the original proximities and, if present, the data weights, the initial configuration, and the fixed coordinates.

MULTIPLE. Multiple random starts. Displays the random number seed and penalized Stress value of each random start.

INITIAL. Initial common space. Displays the coordinates of the initial common space.

HISTORY. History of iterations. Displays the history of iterations of the main algorithm.

MEASURES. Fit measures. Displays different measures. The table contains several goodness-of-fit, badness-of-fit, Stress, and fit values. This setting is specified by default.

DECOMPOSITION. Decomposition of Stress. Displays a objects, rows, and sources decomposition of penalized Stress, including row, column, and source totals.

COMMON. Common space. Displays the coordinates of the common space. This is specified by default.

DISTANCES. Distances. Displays the distances between the objects in the configuration. This keyword must be used in combination with COMMON or INDIVIDUAL to actually produce a table with distances.

WEIGHTS. Individual space weights. Displays the individual space weights, if applicable (that is, if one of the individual differences models is specified on the MODEL subcommand). Depending on the model, the space weights are decomposed in rotation weights and dimension weights, which are also displayed. This setting is specified by default.

INDIVIDUAL. Individual spaces. The coordinates of the individual spaces are displayed only if one of the individual differences models is specified on the MODEL subcommand.

TRANSFORMATION. Transformed proximities. Displays the transformed proximities.

Example

PREFSCAL var01 TO var15
  /INPUT = ROWS(42)
  /MODEL = WEIGHTED
  /PRINT = HISTORY COMMON MEASURES.
  • Here, a weighted Euclidean model is specified with multiple sources.
  • The optional output consists of a table with the history of iterations, the coordinates of the common space, and Stress and fit measures.
