Now we want to explore the hotel Average Daily Rate (ADR: dividing the sum of all lodging transactions by the total number of staying nights) and what might be influencing it. The output in Exhibit 10 below is a regression of ADR on various variables defined as: Y variable: X variables: ADR= = Average Daily Rate for bookings not cancelled for both types of hotels. BookHalfMeal BookFullMeal BookBed Carpark Children Adults Repeatguest = 1 if booking included bed, breakfast, and dinner; and = 0 otherwise. = 1 if booking included bed and all meals; and = 0 otherwise. = 1 if booking included bed only or unidentified; and = 0 otherwise. = 1 if carpark space is needed; and = 0 otherwise = Number of children in every booking = Number of adults in every booking = 1 if it is a repeating booking; and = 0 otherwise. Weekenddnights = Number of weekend nights the guest stayed or booked to stay at the hotel Weeknights = Number of weeknights (Mon to Fri) the guest stayed or booked to. a) Let us now explain and interpret the multiple regression coefficients. (i). State and interpret the intercept. (ii). State and interpret the coefficient on bookfullmeal. (iii). Use the model in Exhibit 10 above to predict the hotel Average Daily Rate for a single adult guest with half board booking, no carpark space, no children, making a first time booking and staying for the weekend nights only (Saturday and Sunday). Show your working. Also, comment on the validity of this estimate.
