Thank you so much. Your comment made me realise that I had posted the code from before I put in the Bayesian priors. It should be an efficient design here. See below for the updated code with your edits incorporated. One other minor question - the price attribute has large gaps between levels so I ...

Hi,
Thank you for all of the help so far. I am about to start a final experiment, following two rounds of piloting to get priors. We have a topic with a lot of conditions, because we are trying to make the experiment as true-to-life as possible, but I am concerned that this may be too much, as the ...

Many thanks for the help with this last year, we put it on hold for a while but will be implementing it soon. I just had one follow-up question from your reply last year: why do we use sobol here in particular? I ask because a colleague suggested that Halton draws should always be used as a default ...

Many thanks for this detailed reply - apologies for asking so many questions in one post!

This all makes sense - two more follow up questions though:

1) Great - I will put in the priors again from my pilot. In this case though, how do I know what my target sample size should be, if the S estimates ...

Hi, thank you for a great piece of software. I have been reading the forums and Ngene manual for a while, but as this is the first time designing with Ngene, I just want to check I have understood correctly before I launch this survey.

I have a labelled experiment with three alternatives plus a no ...
