In this special guest feature, Carol Wells reviews the new book by Scott E. Page entitled The Model Thinker. “A hands-on reference for the working data scientist, ‘The Model Thinker’ challenges us to consider that the historical methods we have used for data analysis are no longer adequate given the complexity of today’s world. The book opens by making the case for a new way of using mathematical models to solve problems, offers a close look at a number of the models, then closes with a pair of demonstrations of the method.”
