DOE allows multiple input factors to be manipulated, determining their effect on a desired output (response). By manipulating multiple inputs at the same time, DOE can identify important interactions that may be missed when experimenting with one factor at a time.
Generalized Regression used in conjunction with a designed experiment may provide answers to questions such as:
- What are the key factors in a process? (Explanatory)
- At what settings would the process deliver acceptable performance? (Predictive)
- What are the key, main, and interaction effects in the process? (Explanatory)
Variable Selection is used to:
- Fit a sequence of models (maybe many models)
- Use some metric to see how well each model fits our data
- Keep the model that fits best
In this video, see how to:
- Compare different models
- Decide on the sequence of models to fit
- Apply technique to some examples
Q&A is included throughout the video.
