Mixed Models Analyses Using SAS®
AGLM : AGLM42
This course teaches you how to analyze linear mixed models using the MIXED procedure. A brief introduction to analyzing generalized linear mixed models using the GLIMMIX procedure is also included.
Learn How To
- analyze data (including binary data) with random effects
- fit random coefficient models and hierarchical linear models
- analyze repeated measures data
- obtain and interpret the best linear unbiased predictions
- perform residual and influence diagnostic analysis
- address convergence issues.
Who Should Attend
Statisticians, experienced data analysts, and researchers with sound statistical knowledge
