Hi I had a previous thread that helped a lot and now I was hoping that I could find help here again.

We still plan an epxeriment to estimate demand elasticities for a certain transport mode. We use three alternatives (one opt out) 3 attributes and 24 choices in two blocks.
We identified price (6 ...

My colleague would still be in favor of a random design in order to capture all different effects of price changes and other attribute changes. We concluded with a compromise to have a larger blocked design of 20 choices in 2 blocks. We will eliminate dominant choices and discuss implausible choices ...

Thank you for the quick reply.

1) We itend to explain explicitly that not choosing Alternative 1 or 2 will mean using another alterantive of which no transport is one. We do not care about the other alternatives to avoid misspecifications and sinc we only care about the transport mode described in ...

I am not sure if the title really represents my questions, but please bear with me for the time being. I am working on the design of a study and I am struggling with the proposed design. We are analyzing different transport choices to estimate an elasticity of demand. Therefore we plan an experiment ...
