Business Knowledge Series tanfolyam

Előadó: Mike Patetta, Analytical Training Consultant, Education Division, 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.

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 SAS Programming 1: Essentials and Statistics 2: ANOVA and Regression or have equivalent knowledge before taking this course.
