In this week's episode Patrick and Greg explore the often neglected method of two-stage least squares; they take a walk down memory lane to explore its origins and then drag it kicking and screaming into the 21st century for much promising use within the latent variable model. Along the way they also mention magic dishwashers, being under-estimated, blind pigs & truffles, Sadie Hawkins, intellectual spinning hook kicks, Fisher's eight-pack abs, the fine print, Winston Churchill vs. Chewbacca, Guinea pigs, Mrs. Lincoln, butter snacks, and snipe hunts.
