- This course is for scientists and analysts who want to analyse observational data collected over time. It is not for SAS users who have collected data in a complicated experimental design; they should take the Mixed Models Analyses Using SAS course instead.
Longitudinal Data Analysis with Discrete and Continuous Responses
Before attending this course, you should be able to
- execute SAS programs and create SAS data sets. You can gain this experience by completing the SAS Programming 1: Essentials course.
- fit models using the GLM and REG procedures in SAS/STAT software. You can gain this experience by completing the Statistics 2: ANOVA and Regression course.
Who should attend
Epidemiologists, social scientists, physical scientists, and business analysts
Learn how to
- create individual and group profile plots and sample variograms
- use PROC MIXED to fit a general linear mixed model and a random coefficient model
- plot information criteria for models with selected covariance structures
- generate diagnostic plots in PROC MIXED
- fit a binary generalized linear mixed model in PROC GLIMMIX
- fit an ordinal generalized linear mixed model and a model with spline effects in PROC GLIMMIX
- fit a binary GEE model in PROC GENMOD.
