Visualizing Independence Using Extended A ssociation Plots

Association plots—a visualization technique for the independence problem i n 2-way contingency tables—are extended in three directions: 1. The visualization is enhanced by using colors for the importance of the resi duals. 2. The implementation currently available in R i s improved using a more modular design and allowing a more flexible specification of plotting parameters. 3. Two methods for the use of multi-way tables are proposed.
