Error in WTP estimation

Hi there,

I have a problem with my ACBC market simulation. Whenever I use the WTP module (to figure out how to compose best products), the following error appears:
"Warning: Results include instances where Willingness to Pay did not converge. This may be due to utility reversals in the price attribute."
I used piecewise price coding and constrained the price attribute negative for HB estimation. Do you have any suggestions what I could change in the estimation or the WTP settings?
Thanks and KR

We could probably make guesses, but I think the better course would be for you to send your project files to the support team and I can take a look to see why that error is being presented.
