In this week’s episode Patrick and Greg talk about the critical and often unmet assumptions underlying the use of measured variables at multiple time points, whether for simple analyses like tests of means or more complex analyses like modeling individual growth. Along the way they also mention: following your blocker, Pascal’s wager, Wikipedia empathy, ham sandwich syllogisms, flying cattle cars, Kennedy babies, Costco bathroom scales, Spirit Airlines, expecting you to bring wine, crying about broccoli, the Audi A series, dead raccoon smell, Joe Walsh, Greg’s abs, copy/paste measurement models, Orlando vs. Fort Lauderdale, moles on spring break, and disturbing artwork.
