The paper is old, and regression on residuals was much more common back in the day. There were notable dust-ups within some small subsets of the physics community due to its use in a few cases. Your book looks like a good read. It's always nice to see someone talk about stopping rules in particular, which is one of the nastiest problems in experiment design for both practical and theoretical reasons--the practical problem is really one of economics, and we just don't train researchers properly for that.
