Define Range

You must define a range for each variable. The maximum value that is specified must be an integer. Fractional data values are truncated in the analysis. A category value that is outside of the specified range is ignored in the analysis. To minimize output, use the Automatic Recode facility (available from the Transform menu) to create consecutive categories beginning with 1.

You must also define a range for each variable that is used to label the object scores plots. However, labels for categories with data values that are outside of the defined range for the variable do appear on the plots.

To Define an Optimal Scaling Range

  1. Select one or more variables in the Variables list.
  2. Click Define Range.
  3. Enter the maximum value for the variable. A minimum value of 1 is displayed. This minimum value cannot be changed.
  4. Click Continue.
