We're excited to announce the addition of LatentGOLD software demonstrations to our popular workshop on Mixture Modeling and Latent Class Analysis. LatentGOLD is an excellent program for fitting these models and there's a FREE academic license. Details here: tinyurl.com/2dfzxr6j

The Strengths and Limitations of Time-Varying Covariate Growth Models - CenterStat Growth models have long been a workhorse of longitudinal data analysis. Whether we are studying reading development across elementary school, depressive symptoms across adulthood, or…

In a recent blog post, we discuss how to evaluate within-person effects of time-varying predictors in models for longitudinal data. Check it out at centerstat.org/the-strength...

Systematic Review This workshop from Mariola Moeyaert focuses on identifying and organizing research with which to conduct a research synthesis or meta-analysis

The most important step in any research synthesis is to complete a systematic review of prior research. Yet many workshops jump straight to meta-analysis, leaving this out. No longer! Check out our new workshop from Mariola Moeyaert centerstat.org/systematic-r...

Foundations of Item Response Theory This workshop from Wes Bonifay focuses on the foundations and application of item response theory, particularly as applied to binary items.

Did you know we recently added a new online workshop on item response theory, taught by the amazing Wes Bonifay (@wesbonifay.bsky.social)? Check it out: centerstat.org/irt/

Foundations of Bayesian Estimation and Inference This workshop from Milica Miočević focuses on the use of Bayesian estimation and inference in the behavioral, social, and health sciences.

In case you haven’t seen, we have a new workshop that provides a clear entry into the application and interpretation of Bayesian statistics, focused on mean comparisons and regression, and laying the foundations for much more complex models (DSEM, I’m looking at you)

Curriculum - CenterStat Use CenterStat Curricular Pathways to build your knowledge and skills with foundations of research methods, measurement/latent variable models, longitudinal data analysis, and data science.

We're excited to announce a new Applied Qualitative Research Pathway consisting of four workshops: Foundations, In-Depth Interviews, Focus Groups, and Thematic Analysis. Foundations is completely FREE. Take the others individually or all together at a discount. centerstat.org/curriculum/#...

If you’ve ever used a finite mixture model, growth mixture model, or latent class/profile analysis, then you know how tricky it is to decide on the optimal number of components/classes. Here’s our take.

Congrats to CenterStat instructor Dan Bauer, whose paper "Enhancing measurement validity in diverse populations: Modern approaches to evaluating differential item functioning" was just named a top-ten cited article for the 2023 volume of British Journal of Mathematical and Statistical Psychology

Which is better: self-paced or live instruction?
Each has advantages, so we're offering optional livestreams this spring for many of our self-paced workshops on quant methods (at no added cost), including our completely free SEM class. Details at centerstat.org

What are modification indices and should I use them when fitting SEMs to my own data? - CenterStat This is a great question and is one that prompts much disagreement among quantitative methodologists. Nearly all confirmatory factor analysis or structural equation models impose…

Modification indices are often used to decide how to "fix" a poorly fitting structural equation model. However, this is a bit like playing with a rusty knife: tempting and fun but potentially dangerous. Learn more at our blog

What is a suppressor variable, and how does this differ from confounding and mediation? - CenterStat A constant source of confusion within the multiple regression model (and the general linear model more broadly) relates to the terms suppression and suppressor variable.

We're all engaging in a bit of suppression these days. Ever wondered how suppression works in statistical models? Our latest blog post dispels the confusion around suppressors that actually *enhance* the effects of other predictors! centerstat.org/what-is-a-su... #AcademicSky #StatsEd #stats

We have two workshops over the next two weeks where we walk through MLM, how to specify, fit, and interpret, with detailed software demos. Have a look if of interest CenterStat.org
