| 07 Jan 2020 | S1E09: Grumpy Old Man & Village Idiot Argue About Reliability | 01:03:18 | |
In this first episode of 2020, Greg and Patrick welcome the new year by offering what listeners have come to expect: no apparent plan for the episode, followed by rambling, circular, and barely internally-consistent discussion. At least they are, well, reliable. In fact, their meanderings lead them to a discussion of just that topic -- reliability. In an impromptu segment they call "Grumpy Old Man & Village Idiot" the Quanti-dudes talk about the often-forgotten but absolutely critical importance of securing high quality measures when addressing substantive research questions, and the severe consequences of failing to do so. In addition to grousing about reliability, they also discuss: questions you can ask in a dissertation defense when you have no idea what is actually going on, Walmart bathroom scales, frisbees on the lawn, toxic masculinity, carnival barkers, sunscreen, Clint Eastwood, and sibling IQ tests. Easter egg alert: listen for a hidden bark from Greg's dog Gus who wants to be let outside! Stay in contact with Quantitude!

Greg and Patrick pursue several topics raised on prior episodes on scale reliability and measurement invariance to their logical conclusion. Namely, they ponder the multitude of persnickety issues associated with putting a set of items into the psychometric sausage maker to grind out scale scores for use in subsequent analysis. In addition to bickering with one another over a host of trivial issues, they also discuss Neil Peart, needless aggression, time travel, rapping the MMPI, paying the reaper, pokes in the eye, circling the drain, and using the word "imbricate."

| 25 Feb 2020 | S1E16: Missing Data: (IF EPISODE=16 THEN EPISODE=-999) | 01:02:10 | |
In Episode 16 of Quantitude, Patrick and Greg have more fun than is probably socially acceptable when talking about missing data. In addition to embracing the Zen-like paradox of "the presence of missing data," they also discuss West Point, "is" versus "are," middle school English teachers, relentless tenacity, talking narwhals, being completely pregnant, taking in shows at Cat's Cradle, circus tents, and books by Richard Bachman.

| 03 Mar 2020 | S1E17: Planned Missing Designs (or, How to Beat a Metaphor to Death) | 01:01:15 | |
Greg and Patrick start with what seems like a reasonable metaphor linking musical compositions to planned missing data designs, and then they proceed to beat it to death. Then, just when you think they've buried it, they dig it back up and beat the carcass some more before eventually just running out of time. In addition to planned missing designs, they also mention the Kenny G paternity test, every trumpet player's sworn duty, tied 16th notes, Benny und die Jets, the Durham Bullhorns, wastebasket toilets, free steak knives, 81 minutes, doors and flashlights, Alyssa, Jay and Sean, and respecting the dart.

| 10 Mar 2020 | S1E18: A Conversation with Katherine Masyn -- The Power of Three | 00:50:05 | |
Patrick and Greg have a blast hanging out with quant super-star Katherine Masyn, arguably one of the coolest people on earth. In addition to talking about professional development, the futility of making plans, and how to make meaningful contributions to science, the trio also discuss the power of three, mad cow disease, evaporated metal films, green laser pointers, mashed potatoes, and Patrick getting schooled on the non-binary nature of life, the universe, and everything else. Finally, for those listeners using Quantitude as a drinking game, you must drink every time Katherine says "et cetera." Cheers! Stay in contact with Quantitude!

Also mentioned: white elephants, nuns fighting, Garfield phones, apology tours, bear poop, the inverse of an eyeball, prune festivals, creative uses for up-lights, Piaget, chutney, Patrick and Gus’s special relationship, Patrick’s tombstone, stupid questions, and getting “Studented."

Greg and Patrick waste an hour of your time drunkenly wandering along the dangerous cliffs overlooking mixture modeling. In addition to exploring the potential promises and unadulterated dangers of mixture models as a mode of scientific inquiry, they also mention drama nerds, hunchbacks, date night for the Lincolns, name dropping, UConn women's basketball, inductive-deductive wishin'-and-a-hopin', Chihuahua heads, cats cradle, and albino gorillas. We hope you enjoy the episode. Stay in contact with Quantitude!
