I am kinda confused with the calculation of Utility of a particular set of attributes and its levels combinations for a particular respondent.
I am using CBC-HB estimates with "None" utility being estimated.
As per the Utility definition, it is a sum of part-worth utilities and a constant.
U (total utility for a respondent for a specific attribute combination) = Constant + Sum ( part-worth utility* attribute (nominal = 1 or 0)
From CBC-HB estimates, I have all the part-worth utilities of the attributes and its levels. I am really struggling with the estimation of the constant value for this combination.
Would anyone be able to help me with this?
