Patrick and Greg explore what it is, where it comes from, what you might be able to do about it, and, possibly most importantly, that it's actually a good problem to have. This episode concludes Quanti•Qamp 2020, with Season 2 of Quantitude coming in August.Stay in contact with Quantitude! Twitter: @quantitudepod Web page: quantitudepod.or... |
| 2020-Jul-13 • 56 minutes S1E34: Quanti•Qamp VII: Being a Lifelong Quantitative Learner Greg and Patrick dedicate Week 7 of Quanti•Qamp to three core topics: mocking one another, how to continue learning both foundational and novel quantitative methods across your career, and mocking one another. Despite their many disagreements, they unanimously concur that the challenge of keeping abreast of newly developed quantitative methods is entirely Kris Preacher's fault. Carry on. And go learn something! Stay in contact with Quantitude! Twitter: @quantitudepod Web page: quantitudepod.org Merc... |
| 2020-Jul-06 • 60 minutes S1E33: Quanti•Qamp VI: Enhancing Diversity in the Quantitative Sciences Week six of Quanti•Qamp welcomes special guest Dr. A. Nayena Blankson, a Professor of Psychology at Spelman College who is a leading national voice in diversity and equity in academia.

The guest Executive Officer is Dr. Rebecca Brock, Associate Professor in the Department of Psychology at the University of Nebraska at Lincoln, who will motivate a discussion about how to build a quantitative culture in your home department or research unit. Patrick and Greg clearly learn nothing about leadership despite Dr. Brock's best ef... |
| 2020-Jun-22 • 58 minutes S1E31: Quanti•Qamp IV: Writing a Pedagogical Quantitative Paper In the fourth week of Quanti•Qamp, neither Patrick nor Greg have read each other's emails about the organization of the episode and thus entirely ad lib a discussion on how one might write a quantitatively-oriented pedagogical paper. Because they are completely unprepared for the episode, they also forget to provide the next QQamp assignment; however, being the seasoned academicians that they are, they will somehow blame you for not completing the assignment, because by now, "you should have known... |
| 2020-Jun-15 • 56 minutes S1E30: Quanti•Qamp III: Quantitative Research Using Existing Data In the third week of Quanti•Qamp, Patrick and Greg ramble semi-coherently about how you might use existing data to drive a quantitative research idea as well as to serve as the foundation for making a unique quantitative contribution. They explore different potential data sources and discuss the variety of ways these might be used in the pursuit of a quantitative research question. They conclude with the next QQamp assignment: identify a small number of existing data sets in your substantive field that you ... |
| 2020-Jun-08 • 54 minutes S1E29: Quanti•Qamp II: Choosing a Journal In the second week of QuantiBootQamp (remember....the "boot" is silent), Greg and Patrick open with what they agree is a pretty bizarre coincidence. They then discuss, with occasional disagreement, how you might select a journal for your own quantitatively-oriented contribution. They conclude with the next Quanti•Qamp assignment: to read the mastheads and editorial board lists of at least three journals that might serve as a home for your quantitative paper. Stay in contact with Quantitude! Twitt... |
| 2020-Jun-01 • 51 minutes S1E28: Quanti•Qamp I: Developing a Research Idea In this inaugural episode of QuantiBootQamp (where the "boot" is silent), Patrick and Greg express their surprise that people seemed to think this was going to be a fun summer camp. They then explore various ways that you might develop a quantitatively-oriented research question embedded within your own area of study, and end by assigning the first Quanti•Qamp assignment: to develop a quantitative research question of your own.

| 2020-May-11 • 58 minutes S1E27: Call To Arms In this, our final episode of the season, we reveal that we have actually been quietly arming sleeper cells around the world and that we are now sending out a call-to-arms for listeners to rise up and become quantitative leaders in their own fields of study. Along the way we also discuss scaling fences, bad business decisions, Henry the Fifth, Braveheart, saddles and horses, sideways fish, Legos, Kapla blocks, meta-nerds, more ice cream sandwiches, pyramid schemes, and knuckleheads. Stay in contact with Qua... |
| 2020-May-04 • 60 minutes S1E26: The Internal Validity Pre-Flight Checklist Greg and Patrick talk about internal validity -- broadly and traditionally -- but also as an increasingly important lens through which to view our information-saturated world, and be responsible, critical, and skeptical members of scientific communities as well as society. Along the way, they also mention gargling bleach, 5G cell towers, vaping lysol, fecal transplants, the problem with firetrucks, Star Trek and causality, Sherlock Holmes, melon-wrapped prosciutto, kitty physics, the regression fairy, tails... |

Along the way they also discuss spring break for octogenarians, spitting on graves, being flabby and unfocused, Milo and Otis, meat on a stick, subway jumpers, understanding square roots, voodoo dolls, ugly babies, Klingons, hostage negotiators, and rejected... |
| 2020-Apr-20 • 62 minutes S1E24: Research in the Time of Corona In today’s episode, Greg and Patrick start a conversation about how COVID-19 has had an instantaneous and lasting impact on research, what we can do about it right now, and what we can be thinking about for the future as we move forward, together. Along the way they also manage to mention... elevators of blood, Joe Exotic, wisdom of crowds, a fatted ox, skinned knees, intellectual judo, I meant to do that, truck drivin’ subtlety, Apollo 13, hitting a change-up, naive optimism, Thomas Kuhn, and losing your b... |
| 2020-Apr-13 • 61 minutes S1E23: Computer Simulation: Carlo. Monte Carlo. Patrick and Greg spend an hour stumbling through the world of Monte Carlo computer simulation methodology as a way of knowing within the quantitative sciences. They also delve into: bad ideas, the Dans in Patrick’s life, unique Zoom backgrounds, typical birth weights, theoretical models underlying reading glasses, Jan Ken Pon, being due, archery, blue and green blox pots, felonious speeding, horse races, and Easter egg hunts.

| 2020-Apr-06 • 63 minutes S1E22: Factor Analysis -- The Good, The Bad, & The Ugly Greg and Patrick are inspired by possibly the greatest Western movie ever filmed as they navigate The Good, The Bad, and The Ugly of factor analysis. In addition to arguing that exploratory factor analysis isn't really exploratory and confirmatory factor analysis isn't really confirmatory, they adroitly traverse topics including sabbatical do-overs, Corona Academy, leeches, tall ship wine, grad school accomplishments, Roz from Monsters Inc., extraverted statisticians, bread pudding, obituaries, th... |
| 2020-Mar-30 • 59 minutes S1E21: Integrative Data Analysis -- The Quest for a Cooperative, Cumulative Science Patrick and Greg are inspired by the community support we are witnessing during this time of crisis, and they expand this discussion into the community of science. They drill down into the collaborative approach of integrative data analysis in which models are fit to data that have been aggregated across multiple independent samples. They also discuss Quarantudesday, setting food on fire, when the cops show up, being a supportive spouse, defense mechanisms, psychometric punches in the face, not doing crappy... |
| 2020-Mar-23 • 62 minutes S1E20: Finite Mixture Modeling & Sir Mixture-A-Lot 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... |
| 2020-Mar-16 • 63 minutes S1E19: Live from The Rusty -- Irish Storytelling & Quantitative Limericks Patrick and Greg celebrate St. Patrick's Day with Irish storytelling of some of their own epic academic fails, interspersed with a selection of quantitative limericks submitted by Quantitude listeners (as well as a few of their own). The final selections are read by a special guest (who, be warned in advance, is a bit grumpy). 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, chutne... |
| 2020-Mar-09 • 50 minutes S1E18: A Conversation with Katherine Masyn -- The Power of Three 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... |
| 2020-Mar-03 • 61 minutes S1E17: Planned Missing Designs (or, How to Beat a Metaphor to Death) 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... |
| 2020-Feb-25 • 62 minutes S1E16: Missing Data: (IF EPISODE=16 THEN EPISODE=-999) 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.Stay in contact with Quantitude!

| 2020-Feb-18 • 60 minutes S1E15: Academia and the Chamber of Secrets Greg and Patrick embark on a free-ranging discussion of many of the things no one bothers to tell you when entering academia, some that were particularly (and often pleasantly) surprising. They also talk about learning to fly, parenting, Richard Russo, Bayesian personality, Craisins, just noticeable differences, crayon giraffes, academic mulligans, final_final_final drafts, dead birds, Britney Spears, volitional reinvention, unconditional atta'boys, and the academic Pez dispenser. Stay in contact with ... |
| 2020-Feb-11 • 64 minutes S1E14: Model Fit & The Curse of the Black Pearl Patrick and Greg take on the topic of model evaluation and fit, particularly as applied to structural equation models. They also discuss compulsive counting, mashed potatoes, letting the horses out of the barn, building model 747s, Jenga, Moses's third tablet, the Pirate Code, demon conferences, and Roo Mates.

| 2020-Feb-04 • 62 minutes S1E13: How Do I Get Scale Scores? Weight, Weight... Don't Tell Me... 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... |
| 2020-Jan-28 • 65 minutes S1E12: Measurement (Non)Invariance -- Can We Ever Fail to Not Incorrectly Reject It? In this episode, Patrick and Greg respond to a call-in question that raises a host of issues revolving around measurement invariance testing. In addition to complaining about horrible terminology commonly used in quantitative methodology, they also address pirate mothers, irreverance, time machines, quadruple negatives, buying firewood, digging up bodies, the Schotz clock, and dumpster fires. There are also return appearances of Whac-a-Mole and the poking stick. Stay in contact with Quantitude! Twitter: @q... |
| 2020-Jan-21 • 56 minutes S1E11: Grants -- Recommendations for Applicants (Disc 2) In Part 2 of a two-part series, Greg and Patrick draw on their experiences with the National Institutes of Health and the Institute of Education Sciences (as grant PI/co-PI, reviewer, panelist, and panel chair) to offer recommendations for those planning to seek funding for their own research projects. They also talk about a thousand monkeys, stages of grief, Southwest vs. Spirit Airlines, proper use of the word "however," Red Bull, and banana peels.Stay in contact with Quantitude!

| 2020-Jan-14 • 54 minutes S1E10: Grants -- The Process (Disc 1) In Part 1 of a two-part series, Patrick and Greg draw on their experiences with the National Institutes of Health and the Institute of Education Sciences (as grant PI/co-PI, reviewer, panelist, and panel chair) to discuss aspects of the grant review process, including the scoring criteria, conflicts of interest, what it's like "in the room," and what happens after grants are reviewed. They also talk about turkey legs, sausage making, acronym-based drinking games, hairy eyeballs, roller coaste... |
| 2020-Jan-07 • 63 minutes S1E09: Grumpy Old Man & Village Idiot Argue About Reliability 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 importan... |

| 2019-Dec-09 • 66 minutes S1E07: Talking to Strangers... About Quantitative Methodology In this episode, Patrick and Greg respond to a call-in question from Alexis, asking about how one describes to another human being what a quantitative methodologist actually is, leading to a broader discussion about how one makes unique contributions to the sciences from a methodological framework. In addition to talking about quantitative methodology as a way of knowing, they also mention: portmanteaus, social skills, druncles, Zantac, half-Transylvanians, NASCAR pit crews, carving a turkey, ice cream sand... |
| 2019-Dec-02 • 29 minutes S1E06: Model Modification and Whac-a-Mole In Episode 6 of Quantitude Greg and Patrick take their very first phone-in question, which seems to confuse both of them as they are on the computer and not the phone. Regardless, they talk with Tessa from the University of Maryland about her question of how to best use modification indices when fitting confirmatory factor models out in the real world. In addition to completely ripping off the Car Talk Guys from NPR, they address The Pod, rusty knives, Applebees, Patrick's favorite game at the North Ca... |
| 2019-Nov-26 • 59 minutes S1E05: The Don Hedeker Tapes -- Interview With a Rock Star In this episode of Quantitude, Patrick and Greg have the pleasure of talking with the always-entertaining and high-energy Don Hedeker, University of Chicago Professor of Biostatistics. They discuss Don's work in nonlinear mixed effects models, the importance of variance as an outcome, and ecological momentary assessment, as well as his advice for graduate students and indeed anyone presenting and writing in our field. Also mentioned in this episode are: getting scooped, day jobs, the Brady bunch, Germa... |
| 2019-Nov-19 • 57 minutes S1E04: Advice for Grad Students -- Our 2 Cents (Exact Value!) In this episode of Quantitude, Patrick and Greg draw on their 50+ years of combined experience to offer what is clearly questionable advice for graduate students. They begin with a discussion of a recent survey of the best and worst ranked jobs possible (spoiler alert: don't be a taxi-driving logger on your newspaper reporter beat). They then proceed to discuss challenges facing graduate students today and provide some advice that might help along the way. During their discussion they also mention warm... |
| 2019-Nov-12 • 56 minutes S1E03: Pop Quiz SmackDown (Volume 1) Greg and Patrick plan the episode around one topic, but things take an unexpected turn as the episode rapidly devolves into a series of pop quiz questions thrown from Patrick at Greg and back again. Rules of engagement are negotiated on the spot: without preparation, each person has 90 seconds to respond to a question of the other's choosing, which is in turn graded and argued over. Pop Quiz questions wind up addressing a range of topics that are core to understanding the thoughtful application of stat... |
| 2019-Nov-05 • 37 minutes S1E02: (Statistical) Power Struggles In the second episode of Quantitude, Patrick and Greg channel the spirits of the two old men from the Muppet show (Waldorf and Statler, in case you're curious) and argue about the relative risks and benefits of statistical power analysis. They also discuss Patrick's mother, leaf blowing, 11 year-old saxophone players, the fortuitous ambiguity of child labor laws, vision in pigs, the poop emoji, and they properly use the word 'persnickety.' Enjoy! Stay in contact with Quantitude! Twitter... |

| 2019-Oct-21 • 25 minutes S1E01: Welcome to Quantitude / Origin Stories In the inaugural episode of Quantitude, Greg and Patrick introduce themselves, describe their goals for the podcast, and talk about their own professional trajectories -- kind of like superhero origin stories, but without the "super" or "hero." They also discuss what not to say in your application to a quantitative graduate program, a lifelong dream of becoming a police officer, building up to a "tight ten," hot yoga, broken legs, army recruiters, parental wisdom, and umlauts. ... |
