Exact conditional tests for cross-classifications: Approximation of attained significance levels

  • Alan Agresti
  • Dennis Wackerly
  • James M. Boyett


A procedure is proposed for approximating attained significance levels of exact conditional tests. The procedure utilizes a sampling from the null distribution of tables having the same marginal frequencies as the observed table. Application of the approximation through a computer subroutine yields precise approximations for practically any table dimensions and sample size.
