Dmitrijs Kass completed this course, spending 2 hours a week on it and found the course difficulty to be easy.
Do not expect any quantitative material in the lecture videos despite the "analytics" in its title. If you don't, then this course will provide you with a good overview of customer analytics, including terminology and intuition. Despite the fact that I was looking for a quantitative course, I really enjoyed it.
For those interested in the probabilistic models behind the material covered, you will be provided with a link to a scientific paper (Customer-Base Analysis in a Discrete-Time) which describes the model in details. Above that it provides a detailed instruction for implementing it in both Excel and Matlab. This is a valuable paper.
