Hi,

When using JMP11, the number of runs for a 4-factors DSD is N=9.

With JMP12, N=13.

Any reason for this?

Thanks

Solution

I believe the number of recommended runs for this very powerful new screening design have evolved based upon experience. In general screening designs imply many factors and the power of the DSD's is experienced by leveraging the effect sparsity principle. With low numbers of factors there is a better chance that effect sparsity will not hold and you will need additional experiments to delineate the model. A better scenario would be to brainstorm an additional 2 factors since the number of experimental runs would be the same (13).
