| Authors: | G A Lienert Christine Wolfrum |
| Abstract: | In order to test against contingency in a 3-way table, simplified X2-formulas are given for (1) the general r xcxl-table, (2) for the rxcx2-table, (3) for the 2x2xl-table, and (4) for the 2×2×2-table. The tests are valid only if a sample of N individuals is observed as to 3 discrete or discretisized (dichotomized) variables which are, under H0, assumed to be totally independent. |
