Enlarging the parameter range of a DSD

JL_LZH

Hello, I have a question regarding the possibilities of enlarging the parameter range of a screening design afterwards.

I ran a DSD where I used e.g. 2 different kinds of nozzle diameters and now, when analysing the results, I think it would be interesting to include smaller nozzle sizes. Is there a way to add runs with those new nozzles to my design, so that I can keep my old results for an "overall-model"? 

Thanks in advance

Select DOE > Augment Design. (This process is documented in Help > Books > Design of Experiments in its own chapter.) Identify the response and factor columns in the original design. Click Augment button at the bottom. This interface is essential the same as Custom Design. Go to the factor definitions and change the range for the new runs. Enter the number of the runs for the new design (original number of runs + number of new runs = total number of runs).
