| Quantlet: | measure | |
| Description: | computes coefficients of association between two partitions which are crossed and build up a contingency table |
| Usage: | m = measure (h) | |
| Input: | ||
| h | k x p contingency table | |
| Output: | ||
| m.r | Rand's coefficient | |
| m.rc | Rand's coefficient corrected by chance | |
| m.fm | coefficient of Fowlkes and Mallow | |
| m.chi | Chi-square value | |
