Numerical Optimization Ramps

Ramps are a graphical view of each optimal solution.

Optimal factor settings are shown with red points.

Optimal response prediction values are displayed in blue.

Responses with models, but no goals are shown with gray.

The Factors Tool is used to control which solution is shown in the graph area. Stepping through the list of solutions is a good way to explore how the factor settings effect the response.

User Tip: Toggle between solutions and observe which points move, thus providing a feel for sensitivity. If you see little movement, the solution is robust.
