To optimize responses for mixture design
main topic     see also 

1    Choose Stat > DOE > Mixture > Response Optimizer.

2    Move up to 25 responses that you want to optimize from Available to Selected using the arrow buttons. (If an expected response column does not show in Available, fit a model to it using Analyze Mixture Design.)

·    to move responses one at a time, highlight a response, then click or

·    to move all the responses at once, click or

You can also move a response by double-clicking it.

3    Click Setup.

4    For each response, complete the table as follows:

·    Under Goal, choose Minimize, Target, or Maximize from the drop-down list.

·    Under Lower, Target, and Upper, enter numeric values for the target and necessary bounds as follows:

1    If you choose Minimize under Goal, enter values in Target and Upper.

2    If you choose Target under Goal, enter values in Lower, Target, and Upper.

3    If you choose Maximize under Goal, enter values in Target and Lower.

For guidance on choosing bounds, see Specifying bounds.

·    In Weight, enter a number from 0.1 to 10 to define the shape of the desirability function. See Setting the weight for the desirability function.

·    In Importance, enter a number from 0.1 to 10 to specify the relative importance of the response. See Specifying the importance for the composite desirability.

5    Click OK.
