Hi,
I am wondering how to calculate this in Minitab. As far as I know other software for statistics sometimes can present that contribution in a graph and give a real %.
I was trying to find it in Minitab and I am confused.
Basically, the standard formula for this is:
p% (PCR) = [Variance (F) x mean square variance error] / total sum of squares x 100%
It seems I cannot get all of the components to calculate it.
Am I doing something wrong?
I can rely on Pareto charts to see which factor has an impact but it's not giving me any "numbers"
Also, as it is seen below, Main Effects are showed together. Is there any way to see these calculations for each factor?
Analysis of Variance for Option 1 (coded units)
Source DF Seq SS Adj SS Adj MS F P
Main Effects 4 1,1104 1,1575 0,2894 1,72 0,201
2-Way Interactions 6 1,4564 1,2768 0,2128 1,27 0,333
3-Way Interactions 4 1,1022 1,1087 0,2772 1,65 0,217
4-Way Interactions 1 0,2175 0,2175 0,2175 1,29 0,274
Residual Error 14 2,3516 2,3516 0,1680
Pure Error 14 2,3516 2,3516 0,1680
Total 29 6,2382
