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!

The hosts discuss the multilevel model and its cool extensions, while also mentioning topics like hostile federal judges, grievances, Sesame Street, distributional baguettes, naive standard errors, intra-class correlation, cross-classified models, and more.

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. Stay in contact with Quantitude!

The discussion uncovers how overlapping variables complicate regression analysis, while playful metaphors illustrate the nuances of predictor significance. Rather than fear multicollinearity, the speakers advocate for embracing it and focusing on core research hypotheses. Expect laughs and insights amid tales of baguettes in space and whiny babies!

In this week's episode, the first of Season 5, Patrick and Greg explore the very cool world of receiver operating characteristic, or ROC, curves: what they are, how they work, and why we can give partial thanks to Winston Churchill for their existence. Along the way they also mention: advent calendars, lasagna for 8, Honey Nut Cheerios, radio detection and ranging, flock of seagulls, broken pun promises, Dwayne Johnson, the whale petting machine, Embassy Suites, poison ivy and kudzu, sexy Hulk, smoldering intensity, Spitfires and F-14s, drunken punches, and Where’s Waldo.Stay in contact with Quantitude!

In the last episode of season 4, Greg and Patrick discuss the very cool exploratory technique of cluster analysis — including concepts of multivariate distance, hierarchical and non-hierarchical methods, and how it differs from mixture models. Along the way they also mention: Scandinavian architects, raccoons on meth, vegetarian hotdogs, sh*t-ton of do-loops, free-range jam, statistical hairballs, Euclid’s burial, the platypus problem, stars and galaxies, stealing from the hard sciences, ungulates & marsupials, and Amy-Marie.Stay in contact with Quantitude!
