Use of freqparcoord for Regression Diagnostics

This is the third in my series of three posts on my package freqparcoord with Yingkang Xie. (My next post after this will show how to use R to explore one of my favorite examples of “what can go wrong” in statistics.) Here is a very brief review of my previous posts regarding freqparcoord. A

Some R Resources for GLMs

by Joseph Rickert Generalized Linear Models have become part of the fabric of modern statistics, and logistic regression, at least, is a “go to” tool for data scientists building classification applications. The ready availability of good GLM software and the interpretability of the results logistic regression makes it a good baseline classifier. Moreover, Paul Komarek argues that, with a...

The freqparcoord Package for Multivariate Visualization

Recently my student Yingkang Xie and I have developed freqparcoord, a novel approach to the parallel coordinates method for multivariate data visualization.  Our approach: Addresses the screen-clutter problem in parallel coordinates, by only plotting the “most typical” cases, meaning those with the highest estimated multivariate density values. This makes it easier to discern relations between variables.
