  1. RSM JMP EXAMPLE A full 23 factorial experiment with 5 center points was completed and the results are shown below: Treatment A B pH Comb.(A)(B)(C)Yield (1) -1 -1 -1 48.7 a +1 -1 -1 55.8 b -1 +1 -1 65.2 ab +1 +1 -1 69.5 c -1 -1 +1 57.8 ac +1 -1 +1 59.1 bc -1 +1 +1 65.2 abc +1 +1 +1 69.2

  2. RSM JMP EXAMPLE And we add five center points to test Lack-of-Fit. Treatment A B pH Comb.(A)(B)(C)Yield center 0 0 0 71.9 center 0 0 0 65.1 center 0 0 0 70.2 center 0 0 0 66.8 center 0 0 0 68.5 Please run a Lack-of-Fit test and draw conclusions

  3. Use the “Fit Model” capability in Analyze to apply to the data

  4. Add the main effects and interaction terms into the model in a way as showed in the previous examples

  5. Click the “Run Model” button to acquire the output

  6. Since the p-value is .0094, there is a significant lack of fit and the star points should be run.
