Specifying a Model

Once you have defined the factors, you need to specify the master model. Do the following:

  1. Click Select Design.

  2. In the Design Specification window, click the arrow and select User defined from the menu.
  3. Select X1 and X2 and change Interaction Effects to Polynomial Effects with the arrow, and then click Polynomial to add quadratic effects to the model.

  4. Select X1 through X6, change Polynomial Effects back to Interaction Effects, and click Interaction to add all the two-way interaction effects to the model.
  5. Click OK. ADX determines that 34 runs are needed for the design.

    user defined model



By default, ADX will pick 10 more runs than the number needed to make a saturated design. You can choose a different number of runs, select Saturated to generate the minimum number of runs given the model, or select Blocking to specify the number of blocks and the number of runs within each block.
