The moment-ratio diagram is a graphical tool that can help you choose a model for univariate data.

This presentation shows how to

• Understand how the diagram connects well-known probability distributions.

• Construct a moment-ratio diagram in SAS 9 and SAS Viya.

• Use bootstrap methods to identify possible models.

• Use a moment-ratio diagram to design a simulation study.

Each topic is accompanied by SAS code, which you can download from a GitHub site.
