The hosts discuss classical test theory and its relation to modern latent variable models. They explore the restrictions of classical methods and ways to relax and test them. They also touch on various random topics throughout the conversation, including fortune cookies, personal experiences, and controversies surrounding reliability measures in psychological research.

In this week's episode Patrick and Greg launch a new occasional series called Stuff You Should Know. The topic for today is regression to the mean: what the heck is it, how does it arise in every day life, and what can we do about it. Along the way they also discuss the space-time continuum, Kai Ryssdal, inflation, witches of MacBeth, the hidden curriculum, oh dang, sh*t (ummm...STUFF) you should know, SAT prep courses, the triumph of mediocrity, angstroms, blobs. reinventing history, and being patronizing. Stay in contact with Quantitude!

Greg and Patrick from Quantitude discuss confidence intervals, including symmetric and asymmetric ones, their misinterpretation, and the significance of constructing them. They also touch on unrelated topics like tire pressure gauge mysteries, conference travel reimbursement, phases of the moon, and more.

In this week's episode Patrick and Greg have great fun talking about meta-analysis with Paschal Sheeran, a social psychologist from the University of North Carolina at Chapel Hill. He describes what meta-analysis is, what it offers, and how to apply it in your own work. Along the way they also discuss taking off into the north vs the south, flipping people off, being subtle, metaphysics, say my name, most effective tactic available, fleeing Ireland, struggling to fit in, falling off a bus, taking the piss out of your own work, opposable thumbs, descriptive descriptions, sleepwalking reviewers, the wild west, the importance of cake, living the dream, and the five stages of meta-analysis. Stay in contact with Quantitude!

The hosts debate whether Die Hard is a holiday movie, discuss statistical ideas that are hard to let go, analyze 'It's a Wonderful Life' and its themes, explore methodological differences, talk about model fit evaluation, and examine the psychoanalytic analysis of 'Die Hard' and holiday sentiments.

In this week's episode Greg and Patrick explore alternative parameterizations of the SEM-based latent curve model to capture various forms of nonlinearity, some that are approximations and others that are exact. Along the way they also discuss Swifties, remastering your life, bull testicles, the world's worst RA job, Yerkes-Dodson law, show a little ankle, the St. Louis Arch, bachelorette parties, deck screws, DIY-ing a model, being a little too quiet, complete nonsense, blasting your pecs, haters gonna hate, the worst day ever, Frankenspline's monster, being left off at the third floor, and looking for a new cohost.  Stay in contact with Quantitude!

In this podcast, the hosts discuss regularization methods such as ridge, LASSO, and elastic net procedures for variable selection. They also touch on topics like bowdlerizing, disturbance in the force, and letting go of truth. They explore the concept of regularization, its applications in statistics, and the tension between explanation and prediction in model selection. The advantages of regularization methods, such as enhanced replicability and handling collinearity, are highlighted.

In today’s episode, Greg and Patrick dig into Confirmatory Composite Analysis, a very clever way to get formative factors and their causal indicators into the traditional structural equation modeling framework, along with any other latent factors and their effect indicators that might already be in the model. Along the way they also mention full-contact Wordle, being grounded, spelling bees, state capitals, definitions of leadership, a many ways, rabbit or duck, set of steak knives, canonical correlation vs. Homer Simpson, secret sauce, Quantitude Word of the Day, Who’s a good boy?, the man behind the curtain, Penn and Tellering, a new symbol, Beavis, and car stereo wiring diagrams.Stay in contact with Quantitude!

In this episode, Patrick and Greg discuss the challenge of incorporating causal indicators in an analytical framework dominated by effect indicators and latent factors. They touch on topics like self-help books, habits, defining terms, and the meaning of IS. They also explore the distinctions between causal formative and composite formative measurement models, and discuss approaches for analyzing these factors. The hosts wrap up by expressing gratitude to listeners, providing subscription information, promoting merchandise, and mentioning the episode sponsors.

In today’s episode, Patrick and Greg talk about fun extensions to the basic confirmatory factor model, including higher order models, bifactor or residualized models, and multitrait-multimethod models. Along the way they also mention microscope lab, burning ants, substitute teaching, Cool or Creepy?, Monet, Clueless, haystacks, hotdogs, What are you thinking?, pennies and pounds, party like it’s 1904, potluck freeloaders, lips and a**holes, promiscuous models, and shock absorbers. Stay in contact with Quantitude!
