Dear Michiel,
I am extremely thankful for your regular help. I have a small doubt regarding dominant alternatives in the choice scenarios.
With the above corrected code, I have prepared different number of choice scenarios such as 24, 36 and 48 in total with 6 choice sets in each block. Although I ...

Re: Difference in level balance when mfederov algorithm is u
Dear Michiel,
Thank you so much for your prompt replies. As per your suggestions, I am correcting my code as below:
design
;alts = Alternative1*, Alternative2*
;rows = 48
;eff = (mnl,d)
;block = 8
;model:
U(Alternative1) = a.dummy[-0.002|-0.0012|-0.001] * A[0,1,2,3] +
b.dummy[-0.002|-0.0012|-0.001 ...

Re: Difference in level balance when mfederov algorithm is u
Dear Michiel,
Thank you so much for your insightful suggestions.
As suggested, I tried dummy coding all the 7 variables (using modified code1 below). I got a doubt which might sound silly. To show that the utility of an alternative is inversely proportional to particular numerical variables such ...

Re: Difference in level balance when mfederov algorithm is u
Dear Michiel,
Thank you so much for your valuable suggestions.
When I increased the prior coefficients of numerical variables from 0.001 to 0.01, the pairwise combinations for 2 unlabelled alternatives remained the same (i.e., only first-last levels and second-third levels as pairs). But, when ...

Re: Difference in level balance when mfederov algorithm is u
Dear Michiel,
Thank you so much for your valuable suggestions. I have a few more doubts regarding the design of unlabelled experiment for my study.
When I dummy-coded all 7 variables, the d-error increased from 0.19 (when numericals were not dummy-coded) to 0.40. To reduce the error, I tried to ...

Difference in level balance when mfederov algorithm is used
Dear all,
This is my basic code. Because priors are not known, I started with zero priors. For the same design, when * and mfederov algorithms are used at a time, there was no attribute-level balance but different possible combinations were found to be present. When mfederov algorithm is not used ...
