In this week's episode Patrick and Greg enlist the help of six quantitative methodological scholars, who share a wide variety of fertile ground for quantitative research, which should be useful for students seeking dissertation topics as well as anyone interested in active methodological areas. Along the way they also mentioned: Kill Bill, The Waltons (with corpses), taking away grandpa's car keys, needing an avocado, Patrick's paygrade, clean-up hitters, unhinged Tweeting, promiscuous models, meercats, cantankerously frequentist, who needs data, and combining with Jordan for 70 points.
