This course is for scientists and analysts who want to analyze 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.

Skills Gained

  • 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.

Who Can Benefit

  • Epidemiologists, social scientists, physical scientists, and business analysts

Prerequisites

  • Before attending this course, you should be able to
  • execute SAS programs and create SAS data sets
  • fit models using the GLM and REG procedures in SAS/STAT software.

When does class start/end?

Classes begin promptly at 9:00 am, and typically end at 5:00 pm.

Does the course schedule include a Lunchbreak?

Lunch is normally an hour long and begins at noon. Coffee, tea, hot chocolate and juice are available all day in the kitchen. Fruit, muffins and bagels are served each morning. There are numerous restaurants near each of our centers, and some popular ones are indicated on the Area Map in the Student Welcome Handbooks - these can be picked up in the lobby or requested from one of our ExitCertified staff.

How can someone reach me during class?

If someone should need to contact you while you are in class, please have them call the center telephone number and leave a message with the receptionist.

What languages are used to deliver training?

Most courses are conducted in English, unless otherwise specified. Some courses will have the word "FRENCH" marked in red beside the scheduled date(s) indicating the language of instruction.

What does GTR stand for?

GTR stands for Guaranteed to Run; if you see a course with this status, it means this event is confirmed to run. View our GTR page to see our full list of Guaranteed to Run courses.

ExitCertified is an excellent provider - I have done 3 courses with one in Virginia so far. My next course will be to ramp up on azure

Had a good time taking course with ExitCertified. The Data Science course with Python was really laid out well and it was very easy to understand and navigate. The setup using Anaconda was really good and it was easy to follow along and do the practise exercises.

It's the first time participating ExitCertified courses. The experience is overall good.

Concise overview of AWS Services and how to correlate those services with exams.

Friendly, easy to use interface. Was very helpful for labs and following along with class material.
