Select Optimal Design

Distance-Based Method - Distance Measures

  

Minitab displays the largest and smallest distances between the selected design points. This value is the Euclidean distance. The difference between the smallest and the largest distance values indicates how uniformly the points are spread in the design space. You can use this information to compare designs.

Response surface design selected using distance-based optimality

 

Number of candidate design points: 20

Number of design points in optimal design: 10

Number of factors: 3

 

Row number of selected design points: 8, 17, 5, 11, 1, 2, 6, 13, 4, 20

 

Smallest distance between optimal points:  3.3636

Largest distance between optimal points:  84.0896

Interpretation

For the tire data, the smallest distance between optimal points is 3.3636 and the largest distance is 84.0896.
