2006-01-10 Too much repeat

I needed a good refershing course about statistics, but this Dummies does not reach it. It is vastly incoherent, trying to make each chapter self-readable with little reference to the previous chapters. As a consequence, there is little structure and too much repeat. It also describes each formula in great detail, at the expense of major points of interests, like quality review, which would deserve a greater focus on practical examples.
