In a post called "So Long and Thanks for All the F-Tests", Freakonomics writes about a new book called Mostly Harmless Econometrics: An Empiricist’s Companion, which they describe as:
...the rare book that captures the feeling of how to go about trying to attack an empirical question; and it does this by working through two or three dozen of the neatest empirical papers of the last decade.... It is also peppered with references to Douglas Adams’s writing — so what’s not to like?
(Freakonomics' post title and the book's title are themselves HHG2G references. I have refrained... for the moment.)
