Exact Conditional P Value Calculation for the Quasi-Symmetry Model
Abstract:Earlier literature introduced a network algorithm for computing an exact test of independence in a two-way contingency table. This article adapts that algorithm to tests of quasi-symmetry in square tables. The algorithm is generally faster than competing Monte Carlo methods, and essentially eliminates the need for asymptotic approximation of P values for assessing goodness-of-fit of the quasi-symmetry model. A macro written for the R computing package is available for implementing the method.
Keywords:Enumeration  Goodness-of-fit  Loglinear model  Network algorithm  Reference set  Sufficient statistic
