Preece, Rogers and Sharpe (PRS) also describe a "Quick and Dirty" evaluation paradigm, which seems to generally refer to informal empirical methods and what Hartson & Pyla call Rapid Evaluation Methods.
In chapter 8, Saffer provides a brief overview of usability testing (empirical method) and a variant of the heuristic evaluation (informal analytic method).
