Minitab experiment question
Minitab experiment question
(OP)
Hi ,
What if I want to conduct a fractional factorial 2^13-5 experiment with minitab , I mean its a 2^13 and i want to make it a fractional factorial of V resolution so it will be 2^13-5 = 2^8 ,,,, can this ever be done with minitab ? can you recommend another software name that can do such experiment
Thanks in advance

RE: Minitab experiment question
I assume you mean 13 factors at 2 levels, in which case a Placket & Burnam or whatever it is called may be more useful.

Personally I'd be running a couple of smaller experiments first, get rid of the rubbish.

RE: Minitab experiment question
This step has already been done , they were even more and got down to 13

RE: Minitab experiment question
- All main factors were as I mentioned before 13 - 5 = 8 , and the number of two factor interactions of interest are 11 . The rest of 2 factors interactions and all 3 factor interactions and above are negligible .
- My concern is to follow the same method exactly as in a researcher's paper so I can check the validity of an analytical equation . ie : I must use the exact method mentioned .
- The result equation is something like :
a = (alpha0) + (alpha1 * r )+ (alpha2 * t )+ (alpha3 * y )+ (alpha1 * u)+ (alpha1 * p)+.............+ (alpha1 * ry )+ (alpha1 * ru )+ (alpha1 * pz )+.....
my goal is to come out with the constants alpha0 , alpha 1 , ... till alpha 19
using the same method (fractional factorial of 2^13-5 = 2^8 , V resolution) using minitab .
