Dear all

Please let me know why F value and P value is not appeared in the minitab.

I used the Taguchi with four factors and three levels and nine runs.

If you see the attached file, you can see it.

Many thanks in advance.

Is this a Minitab 17 format? I have Minitab 16 and cannot open the file.

Hi.

Your experiment has 4 factors (A, B, C, D) and each one consumes 2 DF with a total of 8 DF. Then, MSE could not be calculated and it's necessary for calculating the statistics tests (P and F).

regards.

Licht is correct. I recommend removing factor A from your model. This will free up 2 df for the error term. I recommend using factor A because is has the smallest effect of the 4 factors on the S/N Ratios.
