Hi all,

My data was generated from a DCE aimed at extracting WTA compensation for receiving a low-reliability electricity supply.
To estimate the model in MNL, my initial thought was to force the WTA param. to be positive (i.e. by assigning log normal distribution).
However, since optout was not an option, I'm not sure if this is a good idea.
would be happy to have your insights.

Can you provide us with a bit more detail, please, e.g. a screenshot of a SC task?

Thanks

Sorry for not responding on time. Attached is the screenshot of a WTA menu.

apologies for the very slow reply.

I would use a lognormal distribution indeed. It's not about whether you have an opt-out or not, really, but about whether it would make sense behaviourally for people to have a diferently signed coefficient
