Abstract

This article demonstrates the visual power of continuous smoothing and slicing of multivariate maps, through an example relating the rates of screening tests to colon cancer rates. A new theoretical result provides legitimacy and understanding by demonstrating how the conditional maps are related to the usual single smoothed choropleth map of colon cancer rates.
