I have choice experiment data for estimating farmer's WTP for irrigation water. I asked farmers to choose from a set of 5 choice sets, each choice set containing 3 alternatives and a current status scenario. From each choice set they chose only 1 alternative. I am planning to use clogit to analyze my data. My dependent variable is a binary choice of whether they chose the alternative or not. If i do this each farmer will have 20 mutually exclusive observations from which 5 are selected as yes and the rest as no. Is this approach correct? or there is a better way of defining my dependent choice variable?
