Ex-Ivey PHD student and now University of Calgary professor, Charan Bagga, and I have just published an article. This focused on the teaching of CLV (Customer Lifetime Value).

Showing A Problem Does Not Equal Demonstrating A Worsening Problem
Cathy O’Neil has a great book on big data, Weapons of Math Destruction, but one with a fundamental flaw. The flawed claim is made in the book’s subtitle and permeates throughout the book. The subtitle is: “How Big Data Increases Inequality and Threatens Democracy”. I could find no significant evidence of big data increasing inequality in the book. She shows…

Simpson’s Paradox: Data can be very confusing

Yet, when you combine the data into a single data set the combined table gives you a different result. Data Can Be Confusing Smith explains this using a click data example.

The Secret Axis: Label Your Axis So As Not To Lie

Other problems arise through carelessness; the researcher/manager using the data doesn’t realize they are abusing…

The basic idea behind the piece is an explanation of how to decide upon what marketing metrics to use. This work introduces a new acronym that I’ve produced called the WAITA model.

A Common Marketing Language
A major problem in marketing is that one often has only a general idea of what another marketer is speaking about. “Unfortunately, marketing still does not have that commonality of terminology” (Farris, Reibstein, and Scheller, 2016, page 46). We need a common marketing language. We Lack Shared Meanings A marketer will talk of loyalty and…

Eric Siegel has an excellent book on predictive analytics and vast search. As his title suggests these involve lying, buying and dying as well as a few things that don’t rhyme.
