| Popis: | For animal carcinogenicity study with multiple dose groups, positive trend test and pairwise comparisons of treated groups with control are generally performed using the Cochran-Armitage, Peto test, or Poly-K test. These tests are asymptotically normal. The exact version of Cochran-Armitage and Peto tests are available based on the permutation test assuming fixed column and row totals. For Poly-K test column totals depend on the mortality pattern of the animals and can not be kept fixed over the permutations of the animals. In this work a modification of the permutation test is suggested that can be applied on exact Poly-K test. |
