Combinatorics of pearson residuals and degree of freedom in contingency tables
Shusaku Tsumoto, Shoji Hirano · 2011
This paper gives further investigation on correlation between pearson residuals and degree of freedom in a contingency table. An interesting formula is obtained, where an independent variable in a contingency table will be a fundamental granule of degree of freedom. The structure of formula is also closely related with combinatorial natures of given variables.
