You need to specify model two 'M2' as well as the 'M1' (or more if you wish).
;eff = M1(mnl, d, mean) + M2(rppanel, d, mean) for example. You can apply weights as well as other specifications.
However it will only test the model against rppanel based on the efficincy measure you specify, because of ...

Another query re: rppanel & model averaging approach => Ngene appears to ignore my constraint and require portion of the syntax when I attempt to generate a new design. The same syntax worked fine for my initial pilot survey design using the mnl. Now the generation process comes out with designs ...

(Your guidance is hugely appreciated!)

The model averaging approach offers a great solution to the outlined challenges. (Actually the Bliemer, Scarpa and Rose paper on this very topic offers a very comprehensive overview of the methodology and theory.)

In terms of adopting this approach for my ...

Thank you for the advice.

Model consistency throughout design and estimation is crucial for the efficiency, so as advised I will include small values for my interaction priors - perhaps proportionately to pilot estimates?

I was also wondering whether to include the coefficient estimates found with ...

Dear Ngene Users and Programmers

I am now at the stage of designing my final survey based on pilot survey data of 26 respondents x 10 choice situations estimated using the standard McFadden conditional multinomial logit model. My data has 3 continuous and 3 dummy variables with 4 respective levels ...

Thank you for your advice!
There are a few more concerns I would appreciate a helping hand with:
(a) I was wondering how critical is the S-Estimate for the pilot? You have stated in the manual that this measure is slightly unpredictable due to the random utility assumption of the underlying model ...

Dear All,

I have designed a preliminary survey for an (mnl, d) specification. However, the final model to be estimated will be the mixed logit.
My question is whether (a) I should use the mnl design and perform a pilot survey to obtain distribution estimates which I will then input for the rppanel ...
