The default setting is to use "one" tau to fix the estimates. But users may want to specify different taus for the subgroups of respondents or the subsets of profile-pair combinations. We should allow users to allow more than one "tau" -- e.g., "tau" for male respondents and "tau" for female respondents. Estimate AMCEs/MMs for the two different subgroups of respondents, fix them using our method, and then pool data to calculate the overall fixed AMCEs/MMs.
