Thank you so much for these suggestions.They were very helpful.
Is there any necessity to have Blocks? For example, if we have 48 choice tasks, and we want every respondent to get 8 choice tasks each, so we mention from 1 upto 8 choice tasks in SE. Will it select 8 choice tasks from a pool of 48 ...

I have retried again used this NGENE design command now with near zero priors and preference order for the 2nd and 7th attribute(unlike before where we had only zero priors), as follows (could you please check if this seems correct) :

design
;alts = opt1*, opt2*
;eff = (mnl, d)
;alg = mfederov ...

Yes thats right.I rechecked.Thank you.
1)If the pilot study doesn’t give significant coefficients or does not converge or very large standard errors, can we still use zero priors for the main study? would that lower the efficiency of the results?
Note: I didn’t set any restrictions between speed ...

I looked at the construction of the ''choice'' variable as you suggested and could not find the error. After reshaping, I constructed an 'alt' variable in a new column that just lists two unlabelled alternatives one after the other, twice for each RID facing 8 choice tasks each, and then a 'choice ...

In this case, as we had less time, went on with our main survey without specifying the priors (as last time in pilot they did not come as significant coeffs)
The data received of the main survey was in two parts, wide form Choice data(2 blocks, 8 tasks, 2 alt, 7 attributes with 2/3/4 levels) and 2nd ...

Hello Prof ! We got data from 100 people pilot study, so next step was to find out the parameters to use them in the equation for finding the correct sample size required for main study.
For reaching there, I used the mnl model equation on this data as :
mlogit choice i.AttribA i.AttribB i.AttribC ...

Thanks for the guidance Professor ! I could succesfully run the DCE for pilot and get a d-error of 0.15 which I hope is acceptable.
1) Is there any good way to check if any of my 48 choice tasks from this matrix I imported to SE from NGene , have got any dominant alternatives at all? Or would there ...

Thank you.That helped !

Thank you, I have checked with Svy Engine, they said it should not be a problem, just to treat the variable codes later during estimation phase matching with how its coded in dictionary.
We have a doubt with the three constraints in my code, where I stated that if the speed is slow then price ...

Thank you, that was very helpful. I am trying to look for resources to add such an extra choice task in SEngine.
As I was checking the ''dictionary''section of survey engine , I noticed that all my variables are coded as 1, 2, 3, 4.... and ''Yes'' is coded as 2 and ''no'' as 1. Even for those choice ...
