S5E23 A Rosetta Stone for DAGs and SEM


In this week’s episode Greg and Patrick talk about both structural equation modeling and directed acyclic graphs, or DAGs, where they are similar and where they are different, and try to provide a Rosetta Stone for translating back and forth between the two. Along the way they also discuss pop, garage sales, thinking about excessive thought, roly-polies, potato bugs, been to the cinema, sweet tea, smiley face sub-i, poop hat, the British Museum, fiberglass replicas, love languages, cave drawings, the space-time continuum, coffee shops, a DAGs Czar, We Are The World (with Cyndi Lauper), tennis shoes, and bubblers.
