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 |
