In this week’s episode Greg and Patrick explore alternative parameterizations of the SEM-based latent curve model to capture various forms of nonlinearity, some that are approximations and others that are exact. Along the way they also discuss Swifties, remastering your life, bull testicles, the world’s worst RA job, Yerkes-Dodson law, show a little ankle, the St. Louis Arch, bachelorette parties, deck screws, DIY-ing a model, being a little too quiet, complete nonsense, blasting your pecs, haters gonna hate, the worst day ever, Frankenspline’s monster, being left off at the third floor, and looking for a new cohost.
