I have tried running the analysis for my Max Diff in two ways. Firstly running it inside Sawtooth and secondly making a .cho file and running it in the HB/CBC software.
When I get the results, the results from both methods are very similar but not exactly the same and as far as I can tell I am running them on the same settings. Is there a reason why the two results are slightly different? If so, what is the best approach to use?
