You’ve collected data, and now you’re examining a histogram. You want to fit a probability distribution to the data, but
you’re unsure which distribution might serve as an effective model. The moment-ratio diagram is a powerful graphical tool
that can guide this process. By plotting the sample skewness and kurtosis of your data on the diagram, you can identify
potential distributional models.
This presentation demonstrates:
- How to construct a moment-ratio diagram using
SAS 9 and SAS Viya.
- How the diagram connects well-known probability distributions and families of flexible
distributions.
- How bootstrap methods can help assess which distributions are plausible candidates.
- How to use a
moment-ratio diagram to design a simulation study.
Each topic is accompanied by SAS code that you can apply to
your own data. |
