Example (Paper Helicopter Logistic Regression)

Consider an example with a single choice set with c = 1, experimental ranges, and the prototype designs Assume that there are n1 = 20 people selecting from the prototype designs associated with factor levels x₄ Use the data to fit a model of the form to predict the average utility:

Answer: Calculations pertinent to estimating and maximizing the log-likelihood .The Excel solver was used to estimate the coefficients. These can be used to predict the chance that a customer of a certain income (x₄) would purchase a helicopter with dimensions (x) in a given choice set.
