Designing Experiments

You can design experiments after setting up models. You can design experiments for both stages, local and global. You invoke the Design Editor in several ways from the test plan level:

• Right-click a Model block in the test plan diagram and select Design Experiment.

• You must select (by clicking) a stage to design for (first or second stage) or the following two options are not possible.

• Click the Design Experiment toolbar button .
• Select TestPlan -> Design Experiment.

For an existing design, View -> Design Data also launches the Design Editor (also in the right-click menu on each Model block). In this case you can only view the current data being used as a design at this stage. If you enter the Design Editor by the other routes, you can view all alternative designs for that stage.

See the Design of Experiment Tutorial.

Viewing Designs

The view design facility enables the user to investigate the statistical properties of the current data.

• From the test plan node, select the model stage you are interested in by clicking, then choose View -> Design Data. Alternatively, use the right-click menu on a Model block.

This provides access to all the Design Editor and design evaluation utility functions with the current data rather than the prespecified design. If you have done some data-matching to a design, each data point is used as a design point. You can now investigate the statistical properties of this design.

For two-stage models, viewing stage one (local model) designs creates a separate design for each test.

See The Design Editor or the step-by-step guide in the Design of Experiment Tutorial.
