Longitudinal and Multi-level Modelling Using R

This workshop presents the concepts and intuition for longitudinal and multilevel modeling with detailed step-by-step illustrations and implementation using free software R.  Based on more than 20 years’ teaching and research experience, I will start with an overview of the well-known regression models for their pitfalls and biases if used to analysis data with longitudinal and multilevel structure and I then introduce how to analyze longitudinal and multilevel data appropriately in a step-by-step fashion implemented in free software R. I will briefly review the R so that the participants are not required to have prior knowledge on R. At the completion of the workshop, participants will have a solid understanding of the challenges and problems in longitudinal and multilevel modelling (including two-level and three-level hierarchical linear models). In addition, participants are able to follow the logic steps and examples in the workshop to analyze their own data.
