One of the reasons I enjoy being a member of a book club is that I get introduced to books I would not have chosen myself. The current book club selection is Flight Behavior by Barbara Kingsolver which is the story of what happens to the residents of a small Appalachian town when Monarch butterflies unexpectedly migrate to their town. Imagine my surprise when I read an excellent definition of the old adage, “correlation is not causation” in this novel.
The book before this one was A God in Ruins by Kate Atkinson. The term chi square automated interaction detection appears in this novel about a World War II Halifax Bomber pilot, Ted Todd. It is usually abbreviated to CHAID. For more information on the technique, click here.
I wonder what will be in the next book!
