Introduction to cluster analysis

Not all patients are created equal, but are there subgroups that are more homogenous?

This episode follows the outline of a webinar, that I presented in 2018 during a PSI webinar. I’m introducing cluster analysis and why you as a statistician need to know about it.

The title of the presentation was “Not all patients are created equal, but are there subgroups that are more homogenous?”

If you wonder about questions like:

• Are there segments of patients at baseline?
• Are there different patterns of e.g. symptom development over time?
• Which adverse events occur together?

Cluster analyses is the way to go. The question we’re asking is always “are there similar patients”. In this episode, we walk over a couple of different ways to define similarity.
