1.
Choose DOE > Mixture Design and make the design data table. Remember that to fit a model, the Y column in the data table must contain values, so either assign responses or click the red triangle menu and select Simulate Responses before you click Make Table.
3.
Right-click the model and select Run Script to launch the Fit Model dialog, which is automatically filled with the saved model.
4.
Click Run on the Fit Model dialog.
The hidden-intercept property also causes the R2 to be reported with respect to the intercept model rather than reported as missing.
