| Outline of Final Research Achievements |
We often use intervals and histograms to summarize the given large numbers of numerical data sets. We use the term symbolic data to call such summarized data and data by the aggregation of different data tables.The quantile method transforms the given symbolic data table to a different sized numerical data table by a unified way. Then, we realize various data analysis methods on the transformed data. This research report includes three quantile methods for symbolic data: (1) A hierarchical method of conceptual clustering; (2) Visualization of multidimensional symbolic data; and (3) The lookup table regression model.
