I created an Excel Simulator from "Choice Simulator". When I open the Excel Simulator, the Shares of Preference are not close to the results displayed in the Choice Simulator with the same simulation parameters (Products, attributes for products).
e.g. in the Excel RFC for one of the products, the stated share of preference is 32.33%, s.e. of 4.2%. In Choice Simulator, the stated share of preference for the same product is 20.5%. (the relative share across products in simulation are also all quite different). Have confirmed exponent is the same, number of products is the same, attributes are all the same.
I understand that it may not replicate exactly, but it's quite different
