SPSS中，对于距离测量的对象分作Interval Data、Count Data、Binary Data。 请问这三种Data是什么区别？

Dissimilarity measures
– Interval measure: Euclidean and squared Euclidean distance, Chebychev distance metric, city-block or Manhattan distance, distance in an absolute Minkowski power metric and customized
– Counts measures: Chi-square and Phi-square
– Binary measures: Euclidean and squared Euclidean distance; size, pattern and shape difference; variance dissimilarity measure; and Lance and Williams nonmetric
• Similarity measures
– Interval measures: Pearson correlation and cosine
– Binary measures: Russell and Rao; simple matching; Jaccard; dice (or Czekanowski or Sorenson); Rodgers and Tanimoto; Sokal and Sneath 1 through 5; Kulczynski 1 and 2; Hamann; Goodman and Krusal Lambda; Anderberg’s D; Yule’s coefficient  of colligation; Yule’s Q; Ochiai; dispersion similarity measure; and fourfold point correlation
