  1. 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.

  2. 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.

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

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

  5. Choose “Stepwise” in “Personality”

  6. To perform forward selection, change both the Enterance and Exit alpha value to .05. We then hit “Go”.

  7. We then hit “Make Model”. This is the reslut of forward selection, Temperature and Termination time enter the model.

  8. We then run the model.

  9. All the factors are significant on the .05 level in the model .

  10. Hit “Enter All” . To perform backward selection, change both the Enterance and Exit alpha value to .05 in the Fit Stepwise window. Choose “Backward” in “Direction” .

  11. We then hit “Go”.

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