Patterns of regional travel behavior: An analysis of Japanese hotel reservation data
This study considers the availability of room opportunities collected from a Japanese hotel booking site. We empirically analyze the daily number of room opportunities for four areas. To determine the migration trends of travelers, we discuss a finite mixture of Poisson distributions and the EM-algorithm as its parameter estimation method. We further propose a method to infer the probability of opportunities existing for each observation. We characterize demand–supply situations by means of relationship between the averaged room prices and the probability of opportunity existing.
