Hierarchically clustered (multilevel or nested) data are common in the social sciences, medical fields, and business research. Clustered data violate the assumption of independence required by ordinary statistical methods. Increasingly complex research designs and hypotheses have created a need for sophisticated methods that go beyond standard multilevel modeling (MLM). This “second course” in MLM will introduce a variety of MLM extensions, including cutting-edge multilevel structural equation modeling (MSEM) to handle complex designs and modeling objectives. Throughout the seminar, empirical examples will be presented to illustrate key concepts. A background in structural equation modeling (SEM) is not necessary.

On Day 1 we will begin by reviewing the basics of MLM, including

  • The motivation for MLM
  • Key concepts
  • Equation conventions
  • The univariate two-level MLM with fixed and random coefficients

Mplus will be introduced as a flexible and powerful software environment for fitting basic and advanced multilevel models. Next, we will cover several advanced MLM topics, including

  • Estimating, plotting, and probing interaction effects
  • Modeling cross-classified data
  • Modeling discrete (e.g., binary, count) dependent variables
  • Conducting power analysis for MLM using a general Monte Carlo technique
  • Fitting multivariate multilevel models

On Day 2 multilevel structural equation modeling will be introduced as a general approach for more complex modeling tasks.  After a brief overview of single-level SEM , we will turn to the development of MSEM and the important advantages of MSEM over MLM (e.g. inclusion of latent variables, complex causal pathways, upper-level outcomes, and model fit assessment). Standard SEM and MLM will be recast as special cases of MSEM. Next we will cover a variety of MSEM topics:

  • Multilevel exploratory and confirmatory factor analysis
  • Multilevel path analysis
  • Multilevel structural models with latent variables
  • Multilevel mediation analysis
  • Multilevel reliability estimation
  • Applications to cross-classified and three-level data

Throughout the two-day course, models will be presented in several formats—path diagrams, equations, and software syntax. Data and Mplus syntax for all of the examples will be included in the workshop materials.

Participants in this seminar can expect to gain:

  • Mastery of advanced topics in MLM
  • A deeper understanding of the relationship between MLM and SEM
  • The ability to use multilevel SEM to test complex structural hypotheses
  • Resources to conduct power analysis for virtually any multilevel design
  • The ability to fluently interpret and translate among path diagrams, model equations, and Mplus syntax for advanced MLM and MSEM
  • Documented Mplus syntax templates for fitting a variety of multilevel models.

Who should attend?

This seminar is designed for researchers who have some prior experience with multilevel modeling (e.g., in a seminar, workshop, or course) and who want to deepen and extend their knowledge.  At a minimum, participants should have a good working knowledge of basic principles of statistical inference (e.g., standard errors, hypothesis tests, confidence intervals), and should also have a good understanding of the theory and practice of linear regression. 


COMPUTING

Mplus will be used for all worked examples, but prior knowledge of Mplus is not essential. You are welcome and encouraged to bring your own laptop computer with Mplus installed (including the multilevel or combination add-on). However, this is not required. Participants will still benefit from the comprehensive set of slides and syntax that they can apply at home.  


Location, Format and materials

The class will meet from 9 am to 5 pm each day with a 1-hour lunch break at Temple University Center City, 1515 Market Street, Philadelphia, PA 19103. 

Participants receive a bound manual containing detailed lecture notes (including equations, graphics, and Mplus syntax), examples of Mplus output, and other useful features.

COMMENTS FROM RECENT PARTICIPANTS

“This course offered a comprehensive overview of MLM. It links theory with stats software output and shows what happens “under the hood.” The instructor was very organized, skilled, and questions and discussions encouraged. Best teaching in statistics I have had.”
  David Marcusson-Clavertz, Pennsylvania State University

“I was mostly interested in the MSEM part of the course and Kris Preacher does an excellent job of not only explaining, but demonstrating the correct approach to multi-level SEM. The additionally provided references are also very useful and handy to have.”
  Natalia Lorinkova, McDonough School of Business, Georgetown University

“I’m grateful for the opportunity to learn from Kris Preacher in the Multilevel Modeling: A Second Course. We covered more topics in two days than I did in two semesters of graduate coursework. Looking forward to taking more courses from Statistical Horizons in the future.”
  Brennan Rhodes-Bratton, Mailman School of Public Health, Columbia University  

“This course provides a great overview of both MLM and SEM, then links them together. The instructor balances explanations of theory and the mathematics underlying the models with clear worked examples of running code and generating results using Mplus.
  Nicole Hallinen, Temple University

“This was an excellent course. It clearly demonstrated the power of the techniques in conjunctions with the power of Mplus.”
  Jacqueline Mogle, Pennsylvania State University

“Kris has an exceptional expertise and clarity in dealing with rather challenging topics. It’s a special learning experience to listen and ask questions to a leading methodologist.”
