Multilevel Modeling of Hierarchical and Longitudinal Data Using SAS

This course teaches how to identify complex and dynamic patterns within multilevel data to inform a variety of decision-making needs. The course provides a conceptual understanding of multilevel linear models (MLM) and multilevel generalized linear models (MGLM) and their appropriate use in a variety of settings.

Apprendre à

• use basic multilevel models
• use three-level and cross-classified models
• use generalized multilevel models for discrete dependent variables.

A qui s’adresse cette formation ?

Researchers in psychology, education, social science, medicine, and business, or others analyzing data with multilevel nesting structure

Before attending this course, you should

• preferably, be familiar with the basic structure and concepts of SAS (for example, the DATA step and procedures)
• be familiar with concepts of linear models such as regression and ANOVA and with generalized linear models such as logistic regression
• be familiar with linear mixed models to enhance understanding, although this is not necessary to benefit from the course.

It is recommended that you complete Programmation SAS I : les fondamentaux and Analyse statistique - Niveau 2 or have equivalent knowledge before taking this course.
