Thank you Dr. Bliemer. It worked and didn't take even a full minute to finish. However, it showed 0% D-Optimality, which I think don't need to affect the design it generated since in other post, you told that "We found a bug in the implementation, which only occurs in some cases with 5 or more ...

I got to realize what you meant by " your attribute levels need to be consistent with the number of rows to ensure attribute level balance." Since It isn't possible to have the same number of rows in all attribute levels in our case, i think it is best to stick to D-efficient model.

Thank you Dr. Bliemer for your prompt response. I used the following syntax but it showed that "Error: An attribute has the wrong number of levels for dummy or effects coding. 'tillage_practice_change' ".

I even reduced the carbon payment levels from 5 to 4 and used rows= 36 and block =4, and ...

It did magic. Thank you Dr. Bliemer. I have been trying to do both Optimal orthogonal and D-efficient design and compare. I had used D-efficient before but this is my first time for Orthogonal design. Can you please check if my syntax is correct or not, for Optimal Orthogonal Design? Thank you in ...

Hi Prof Bliemer and all,

I am trying to generate a design through D Efficient MNL model but it keeps showing error.
• I am generating three alternatives, Opt. A, Opt. B and Neither
• I am generating 30 choice sets in five blocks and I need to use the reject constraints.
• For the prior values, I ...

Prof. Bliemer and the team,
I used the following syntax and generated the design:

Attribute and Attribute Levels

A.Farm practice change

1.Conventional till to no-till
2.Conventional till to conservation till
3.Conservation till to no-till
4.No cover crops to cover crops
5.No change in ...

Hi Dr. Bliemer,
I edited the design a bit but the problem is, when runnning it says that there are many constraints, not having enough attributes or attribute levels for the number of rows required, and the use of too many scenario attributes. Can you please run this model and suggest me if I ...

Prof. Bliemer,
Yes, I meant to ask about attribute level balance. Thank you for your response. I am clear now.

Hi team and Prof. Bliemer,
Following are the attributes and attribute levels of my research:


Attribute:
Farm practice change

Attribute Levels:
1.Conventional till to conservation till
2.Conventional till to no-till
3.Conservation till to no-till
4.No cover crops to cover crops
5.No change in ...

Thank you prof. Bliemer and sorry for my blunder in posting question in another thread. I am again following you here, so that we won't get confused. I have been trying to run this model but it has been super slow. Can you please check , if there is any problem in the model? Again, thank you very ...
