UC Merced Quantitative Methods Measurement & Stats

🎉New Pub in Structural Equation Modeling! What happens to model fit when assumptions fail in Bayesian latent mediation models? Haiyan Liu, Ihnwhi Heo @IhnwhiHeo, Aleksandr Ivanov @IvanovAlex21170, & Sarah Depaoli put it to the test. See what holds up! 🔗doi.org/10.1080/107055…

Check out this new paper in @JAMAPediatrics that I did the analyses for!

📢 Our grad student, Fei Gao, is presenting at #IMPS2025 @pmetricsoc! He will be sharing his work on addressing misclassification in binary variables within mediation analysis! He's excited to connect with researchers from around the world! #QuantitativePsychology #Psychometrics

🚨New Pub! Led by Sarah Depaoli, with Fan Jia and Marieke Visser (our proud alum, now at @UNCG), our paper is out in Structural Equation Modeling! We show how small-variance priors in Bayesian SEM can uncover hidden effects in LCA models. Check it out: doi.org/10.1080/107055…

🚀Ready for takeoff! Ihnwhi Heo (@IhnwhiHeo) is taking the stage at #APS25DC Methodology Flash Talks & Networking by @PsychScience! He'll present his newly accepted Behavior Research Methods paper on recovering knot locations in Bayesian piecewise growth models. Come and connect!

🎉 Cheers to our first-year quant student, Fei Gao, for delivering a great first-year talk! Fei presented on extensions of mediation analysis models with binary variables. A wonderful wrap-up to the year!

🚨Catch our grad student Yue Li at WPA @WPAwesternpsych! She's presenting a simulation study on multilevel mediation models with small samples, focusing on estimating indirect effects using ML and Bayesian methods. Into multilevel SEM, mediation, or missing data? Don't miss it!

📢ICYMI: Our grad student, Alexandra Kislyonkova, is at #NCME! She's presenting her new diagnostic classification model to push the boundaries of psychometrics and educational measurement. Stop by and say hi, she'd love to connect, chat, and share her insights🔥 @NCME38 #NCME2025

📈 Proud moment! Quantitative Methods, Measurement, and Statistics (QMMS) group is part of this momentum. Our group is young but growing impressively, with a strong record of impactful pubs and methodological contributions to the field 👏 Big clap to all our amazing quant folks!

📢 Pub Alert! New paper in Structural Equation Modeling on parameter recovery under misspecified latent mediation models in the Bayesian framework. Led by Haiyan Liu, with Ihnwhi Heo (@IhnwhiHeo), Sarah Depaoli, & Aleksandr Ivanov. tandfonline.com/doi/full/10.10… Congrats to the team!👏

🎉Attention! Check out the latest open-access publication from our graduate student, @IhnwhiHeo! 👏 We're excited to highlight this contribution!

Happy Saturday! As part of JSP's special issue on Bayesian Methods, read Heo et al.'s (2024) article on "Bayesian approach to piecewise growth mixture modeling: Issues and applications in school psychology" authors.elsevier.com/sd/article/S00….

@PsychScience 📢 Our graduate student, Madelin Jauregui, with her lab mate Ihnwhi Heo and advisors Sarah Depaoli and Haiyan Liu, will present a poster on the performance of Bayesian fit indices for enumerating classes in growth mixture models. Be sure to visit her! #aps2024sf @PsychScience

@PsychScience 📢 Our graduate student, Aleksandr Ivanov, along with his advisor, Haiyan Liu, will be presenting a poster on the Bayesian exploration of bifactor exploratory structural equation modeling. Doesn't that sound exciting? #aps2024sf @PsychScience

📊 Our team of quantitative methodologists is gearing up to present at the Association for Psychological Science! Stay tuned for highlights from our presentations. #aps24sf

📢 Join us for our symposium on "Model Fit Assessment of Bayesian Structural Equation Modeling”! Speakers include Sonja Winter (@winterstat), Ihnwhi Heo (@IhnwhiHeo), and Haiyan Liu, with Sarah Depaoli as the discussant. @PsychScience #aps2024sf
