Bchoice proc-weighting function for attribute

[TienThong2017]

Dear all,

I am using Bchoice proc to estimate a brand choice model, in which I want to add cosnumer's uncertainty about attributes in the choice experiment. The utility function is:

U= alpha+beta*X + gamma*w(P)*Y+error

Where X and Y are product's attributes, w(p) is a weighting function measuring consumer's uncertainty about attribute Y:

w(P)=f(delta|P), for example: w(P)=P^delta

P is consumer's answere about their uncertainty on attribute Y (in %) and delta is parameter of weghiting function needed to be estimated.

Does Bchoice allow users to add this weighting function? I apprcieate very much for yoru advises.

Thank you.
