Chaid, английский
- Chaid is a classification trees program developed by kass (1980) that performs multi-level splits when computing classification trees for discussion of the differences of chaid from other classification tree programs, see a brief comparison of classificat
- Автоматическое выявление взаимодействия по методу хи-квадрат
- An early follow-on to the automatic interaction detection (aid) technique, it substituted the chi-square tests on contingency tables for the earlier techniques` reliance on normal theory techniques and measurements, like ttests and analyses of variance. the method performs better on many n-ary attributes (variables) than does the aid technique. but the method still suffers due to its reliance on repeated statistical significance testing, since the theory that these tests rely on assumes such things as independence of the data sets used in repeated testing (which is clearly violated when the tests are performed on recursive subsets of the data). see also: automatic interaction detection, classification and regression trees, decision trees, recursive partitioning.
