If you have a 2-level L4, L8, L16, or L32 design, you can use Analyze Factorial Design to display the alias structure.
For example, you create an L8 Taguchi design with three 2-level factors. You enter the factors in C1, C2, and C3, and the responses in C4 and C5. To display the alias structure:
- Choose .
- In Factors, enter C1 C2 C3.
- Click Low/High. Click OK in each dialog box.
- Choose .
- In Responses, enter C4. Click OK.
Minitab displays the alias structure. You can disregard the other output.
Note
To analyze the design, you must re-define it as a Taguchi design.
- Choose .
- In Factors, enter C1-C3. Enter a signal factor if applicable. Click OK.
