The columns to be analyzed. These must have a Numeric data type.

A column or columns whose levels define separate analyses. For each level of the specified column, the corresponding rows are analyzed using the other variables that you have specified. The results are presented in separate reports. If more than one By variable is assigned, a separate report is produced for each possible combination of the levels of the By variables.

Note: When using a distance matrix, the By variable requires a full matrix for each level of the By variable.

MDS supports two data formats:

Distance Matrix

A full symmetric or lower triangular matrix where the number of rows equals the number of columns).The diagonal entries can either be zeros or missing.

A set of columns that contain measures of a quality or characteristic of an object. The objects are typically named in a column. The object column is not used in the analysis but rather is used as a label for the data points on the MDS plot.

Supported transformations are Ratio, Interval, and Ordinal.

No transformation used.

Data has an ordering from smallest to largest, the differences between values have meaning, and the scale has a true zero. Used to scale the MDS plot.

Data has an ordering from smallest to largest and the differences between values have meaning. Used to scale and shift the MDS plot.

Data has an ordering from smallest to largest. Used for ordinal data.

The number of dimensions for the visual representation of the proximities among your objects. Typically, two or three dimensions are used. With greater than three dimensions, the visualization becomes complex.

Note: The dimension selected can be between 1 to n - 1 where n = the number of objects, otherwise the dimension is set to 2.
