Dear Ngene team,
I have done a D-efficient design using Ngene for my study and I am doing data analysis part.
One question: if I did not specify interaction terms in my utility function used for experimental design, can I still include the interaction terms in MNL models? Any mistake or possible ...

Re: Eval command to re-block
Thanks Andrew.
This works! Excellent! Thank you so much! Now I got 40 blocks instead of original 20 blocks within the original design.
May I ask one more question?
Since the original design is efficient not orthogonal, so blocking here actually cannot ensure attribute level balance right? So ...

Eval command to re-block
Hi,
This is my original design with 20 blocks with 10 choice sets in each block. Now we would like to reduce the number of choice sets in each block such as only five. Then we will need 40 blocks instead of 20. Can I just use eval command to achieve this? Will eval command generate the new choice ...
