2003年 3月16日 | A HIERARCHICAL STRUCTURE FOR SUBSETS | BACK >> 目次 |
● A hierarchical structure for subsets If and when there are many "partition" codes in a set, you're expected to create a "hierarchical" structure of subsets fanned out by as many as the "partition" codes as noted below:
Business Office:{BO-NO, BO-name, by location, by capital formation, ...}[ R ]
Among subsets, no "intersection (conjunction)" will ever be observed--there cannot be a person of both "man" and "woman." There ARE, however, in "real" data, subsets between/among which a conjunction may be observed, I'll take the conjunction next time. |
