Hi,
I want to use D-efficient design to generate choice sets for my choice experiment. I have generated 4 blocks with a total of 40 choice sets and included 3 alternatives (Option A, Option B and Neither) in a choice set.
Regarding the attributes and levels, I have 4 attributes (Price, CF, HR, T ...

Hi,
I want to run an optimal orthogonal design in NGene using the attributes and levels mentioned below. I am new to optimal orthogonal designs in NGene. There is slight revision in attributes and levels.

Price ($/lb): $2.5, $5, $7.5, $10
Feedlot: Grass-finished, Grain fed, No label
Carbon-friendly ...

Thank you for explaining the process.

Hi,
I am just curious how do we do balancing of attribute levels in the ngene design. Can you please explain how to did you put (6-12, 6-12, 6-12, 6-12) for balancing price levels?

Thank you so much for your help.

Thank you for pointing those issues. I have revised my priors looking into the literature.

The revised Ngene syntnx is,

Design
;alts= optA*, optB*, Neither
;rows=36
;eff=(mnl,d, mean)
;block=6
;alg= mfederov
;bdraws=gauss(3)
;model:
U(optA) = b1 [(n, -0.2395, 0.103)] * price[2.5, 5, 7.5, 10]
+ b2 ...

Hi,
I am designing a choice experiment for my research project. I want to use efficient design to generate choice sets for my choice experiment. I am thinking to generate 6 blocks with a total of 36 choice sets and include 3 alternatives (Option A, Option B and Neither) in a choice set.
