Visualizing Independence Using Extended Association and Mosaic Plots

Two visualization techniques for the independence problem in 2-way contingency tables—assocation and mosaic plots—are extended in two directions: 1. The visualization is enhanced by displaying the significance of an appropriate test for independence and by using improved color schemes. 2. The implementation in the R system is improved using a more modular design and allowing for more flexible specification of plotting parameters. Furthermore, some enhancements for displays of various types of independence in general multi-way tables are suggested.
