Note: This tutorial was based on an older version of the abalone data that had a binary old varibale rather than a numeric age variable. It has been modified lightly so that it uses a manual old variable (is the abalone older than 10 or not) and ignores the numeric age variable. Materials prepared by Rebecca Barter. Package developed by Max Kuhn. An interactive Jupyter Notebook version of this tutorial can be found at https://github.
