Multidimensional Scaling

The Multidimensional Scaling (MDS) process estimates the coordinates of a set of objects in a space of specified dimensionality that come from data measuring the distances between pairs of objects. The input data is usually a distance matrix, which can be created by the Distance Matrix and Clustering process. A 2D or 3D Scatterplot is generated based on the estimated coordinates.

MDS can be used as a data exploration tool to identify grouping patterns in the data.

For a more detailed description of MDS, refer to the SAS/STAT reference manual on PROC MDS.

What do I need?

One Input Data Set is required to run the Multidimensional Scaling process. This data set should be a square matrix. The adsl_diit_dmt.sas7bdat data set (from the included Nicardipine data) contains a square matrix.

The adsl_diit_dmt.sas7bdat data set was generated as previously described (see Distance Matrix and Clustering) from the adsl_diit.sas7bdat data set.

For detailed information about the files and data sets used or created by JMP Life Sciences software, see Files and Data Sets.

Output/Results

The output generated by this process is summarized in a Tabbed report. Refer to the Multidimensional Scaling output documentation for detailed descriptions and guides to interpreting your results.
