Abstract:
|
We extend a previously developed exact trend test for correlated binomials in order to compare clustered ordinal multinomials. We also suggest a modification that allows within-cluster variation with respect to the investigative factor (e.g., dose group), when analyzing either correlated binomials or multinomials. We use examples to illustrate the method and its implementation in the StatXact software package.
