Hi all,

      I use STATA to analyze discrete choihce experiment. My choice design has 32 choice sets with each 2 options (A and B). Each option include 3 factors: price (13,15,17), brand (AA,BB), labeling (animal,plant). The choice set will look like this.
                 Option A                           OptionB
    price                    13                                       15
    brand                   AA                                        BB
   labeling          animal                               plant

           From 32 choice sets is divide into 4 block with each 8 choice sets. Each individual (100 individuals) get 1 block (8 choice sets) and ask to choose between option A or B.

    choice = 1 chosen option, 0 not chosen option
    set = same for two alternatives for each set i.e. there are 32 choice sets, it is repeated number from 1 to 32 and start it
          again for the next 32 choice sets.

This is the code; clogit choice price brand labeling, group(set)

I also want to include individual characteristics; gender, income, age. how I can do it?

How I can calculate the probability from people choosing choice?  

Any suggestion would be great.
