🎉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!

[Johnny Felt, Ph.D. @JFeltPhD]

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

🚨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.

🚀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!

[UC Merced Quantitative Methods Measurement & Stats @UCM_QuantPsych]

🎉 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!

[UC Merced Quantitative Methods Measurement & Stats @UCM_QuantPsych]

🚨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!

[UC Merced Quantitative Methods Measurement & Stats @UCM_QuantPsych]

📢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🔥
