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.

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.

Coffee/tea and light snacks will be provided in the morning and at each break.

To keep the costs down, lunch will not be provided, however there are plenty of options for lunch in the area.

The workshop will be held in room OJN 110 at the Centre for Continuing Education at McMaster University at 1 James Street North, Hamilton, Ontario, Canada. The building is located on James Street North, between King Street and King William Street.
