Note: The axes of prediction profiler traces range from the defined upper and lower bounds of the factors, p1, p2, and p3. When you explore the effect of a component and the limit of a second component is reached, it cannot move further and only the third variable changes to maintain the mixture constraint.
2.

To the visible profile curves to bounds that take into account the levels of all three components, click the Prediction Profiler red triangle and select Profile at Boundary > Stop at Boundaries.

3.

To optimize the mixture components click the Prediction Profiler red triangle and select Optimization and Desirability > Desirability Functions.

4.

Click the Prediction Profiler red triangle and select Optimization and Desirability > Maximize Desirability to obtain the optimal factor settings for maximum Y.

The profiler in Maximum Desirability in Profiler for Mixture Analysis Example, displays optimal settings (rounded) of 0.6350 for p1, 0.1557 for p2, and 0.2093 for p3, which give an estimated response of 19.5703.
