JMP Example 7
Build a model using JMP data table stat_7_data with potential factors: temperature, A/B feed ratio, and
Termination time and the response variable yield. Determine which terms are
significant. Build the model using forward and backward selection
technique.

As has been shown in previous examples, open JMP and input the data.
As has been shown in previous examples, open JMP and input the data.

Again, we will be using the “Fit Model” operation on this data.

As was shown in the previous example, the model specifications are made.

Choose “Stepwise” in “Personality”

To perform forward selection, change both the Enterance and Exit alpha value to .05.
We then hit “Go”.
![Page 8: JMP Example 7](https://reader036.fdocuments.in/reader036/viewer/2022081501/56812cfe550346895d91d549/html5/thumbnails/8.jpg)
This is the reslut of forward selection, Temperature and Termination time enter the model.
We then hit “Make Model”.

We then run the model.

All the factors are significant on the .05 level in the model .
![Page 12: JMP Example 7](https://reader036.fdocuments.in/reader036/viewer/2022081501/56812cfe550346895d91d549/html5/thumbnails/12.jpg)
To perform backward selection, change both the Enterance and Exit alpha value to .05 in the Fit Stepwise window.
Choose “Backward” in “Direction” .
Hit “Enter All” .

We then hit “Go”.

The result is the same as in the forward selection. Temperature and Termination time are kept in the model.
