Set the lowest preferred level as base category

[Vince Vo]

I have a choice experiment with conditional logit result. There are 5 attributes with different combinations of 2 levels and 3 levels. May I ask how do I set the least preferred attribute level (largest negative values) as base then it will be easier for interpretation?

Much appreciated.

Figured it out. Just need to set :

global xvar (name of all attribute levels that you see they have higher coefficient after testing)

Please ignore the bracket in the code above when you code in Stata.
