Two-Dimensional Graphical Representations of Regression Submodels.
In the framework of regression, consider the set of regression submodels. By submodel, we mean on e or more response variables and a subset of the potential regressors. Imagine the submodels as a ponts in some space. How can we "project" these ponts onto a map so as to visualize and compare them, with intent to isolate a small cluster of submodels having disirable properties? The core of the idea developed here is geometrical.
