This is awesome! I haven't read the whole manual, yet, but just based on the introduction and the couple of sections I breezed through, this is going to be well worth a more in depth read. Given that this manual predates several modern analytic techniques, I will be interested in what he recommends for techniques.

How did you come across this? Do you have any idea why this is not more commonly referred to, or has not been revised and repubbed, as far as I know?
