Multilevel Modeling

This two-day hands-on workshop covers various topics in multilevel modeling with continuous and categorical variables. Topics include:

  1. When multilevel analysis is necessary
  2. Multilevel regression
  3. Random slopes and cross-level effects
  4. Multilevel confirmatory factor analysis and the MIMIC model
  5. Multilevel path analysis
  6. Multilevel mediation and moderation
  7. Multilevel latent variable modeling and longitudinal data
  8. A-priori and post-hoc power analysis

Examples will be demonstrated in both R (using R-Studio) and Mplus. Syntax and output for both programs will be provided for all examples covered in the workshop. Registration and payment can be made directly online. We accept Visa, MasterCard, American Express, Cheques and Email Transfers. We offer discounted pricing for graduate students and post-doctoral fellows.

  1. Nested data structures
  2. Intraclass correlation and design effect
  3. Effects of ignoring clustering
  1. Fixed vs. random effects
  2. Intercept only model
  3. Adding level 1, 2, and 3 predictors
  1. Centering
  2. Random slopes
  3. Cross-level interactions
  1. Multilevel CFA with level 1 and 2 predictors
  2. Micro to macro relationships
  3. Macro to micro relationships
  1. Multilevel mediation
  2. Bootstrapping standard errors
  3. Bias-corrected confidence intervals
  1. Multilevel moderated mediation
  2. Plotting multilevel effects
  1. Multilevel latent variable modeling
  2. Longitudinal data within a multilevel framework
  1. A-priori power analysis for sample size
  2. Post-hoc power analysis

This workshop is for anyone interested in learning how to deal with clustered/nested data (ie: students nested within teachers) within a multilevel modeling framework. Participants are encouraged to have a working knowledge of multiple regression and an advanced understanding of structural equation model (see our Advanced Structural Equation Modeling workshop here).

No prior knowledge of Mplus or R is required.

For this hands-on workshop we will be working with both R (using R-Studio) and Mplus. For those who are not working with any specific software, we provide all syntax and output for each example to allow for participation without the use of any software.

The R software is available as a free download here, and the R-Studio software can be downloaded for free here.

If you do not own a copy of Mplus, a free but limited demonstration version is available for download at the Mplus website. To run all of the examples used during the workshop, it is recommended that participants have a licensed copy of the Mplus Base program.

Handout materials and datasets will be provided.

Registration will continue until the workshop begins. If you need to cancel your registration, please contact us at
