    <Paragraph position="0"> We have validated the technique using cross-validation on unseen Dutch dialect data (Nerbonne and Heeringa, 1999). The map in Figure 1 distinguishes Dutch &amp;quot;dialect area&amp;quot; in a way which nonstatistical methods have been unable to do (without resorting to subjective choices of distinguishing features). Ongoing work applies the technique to questions of convergence/divergence of dialects using dialect data from two different periods. Finally, the MDS analysis gives mathematical form to the intuition of dialectologists in Dutch (and other areas) that the material is best viewed as a &amp;quot;continuum&amp;quot;. The map is obtained by interpreting MDS dimensions as colors and mixing using inverse distance weighting.</Paragraph>
