Hi all,

As far as I can see in the manual, there is no option to optimize a design for Latent Class models. What would you recommend doing if I assume preferences according to an LC model. I thought that maybe a design of designs approach would be a solution, but I am not too sure if that would ...

Thanks a lot! Yes, this would be what I need.

My idea was to use the same start design (I used an orthogonal), but that also did not help.

Anyways, looking forward to this feature in the next release.

Kind rgds,

Hi,

I want to make sure my NGENE code produces the exact same designs everytime i run the code. I was thinking that there would be an option to set a seed (e.g. for the swap algorithm to find the starting design and do the randomisation) but cannot find anything on that in the manual or the forum ...

Hi there,
i just wanted to ask if there are any news on this topic. I would love to run Ngene in batch mode. Not to run it overnight, but to start it from another source (software). This is for example helpful when I want to simulate several experiments with the same model but different designs ...

Hi there,

I would just like to add a point to curing the problem of dominant alternatives in orthogonal designs and then pose a question concerned with blocking using the eval Option.

1. There are at least two ways to reduce the number of dominant alternatives. First you may change the order of ...

Dear Forum Members,

I am designing a Discrete Choice Experiment containing two alternatives plus one fixed alternative(all level being fixed to 1 (in one case 0)) and an opt out alternative. In total hence there are four alternatives
To generate the design, I am wondering what would be a good ...
