Hi NGENERs
I am writing to learn from your experience. What is the size of a decent pilot study that allows to estimate sufficiently precise priors to construct a Bayesian d-efficient design for the main study? I saw that, in Bliemer & Rose 2011 Transp Res A, you used a small sample of 36 ...

size of efficient designs
Hi Ngeners,
I just read Bliemer&Rose (Transp Res A, 2011) in which you compare estimates from SC surveys based on three experimental designs: an orthogonal design with 108 choice situations blocked into 18 x 6 choice tasks; a D-efficient design with 108 choice situations also blocked into 18 x six ...
