Data

The data below are used in the book 'Modern Multidimensional Scaling' (2nd edition) by Borg and Groenen (2005). Some of the data are used in the text, others in the exercises. For each data set, four files are given:

• an ASCII file with the description of the data (*.des),
• an ASCII file with the raw data (*.dat),
• a Microsoft Excel file with the data (*.xls), and
• an SPSS file (version 12) with the data.

Similarity and dissimilarity data are always given in symmetric form. The data are organized according to the chapters in the book. For each chapter, there is a separate page giving all the descriptions of the data sets.

You can also download all data files in a zip-file from here.
