that tourists with higher income level tend to decide their destination
by considering the existence of travel party (latent class 1) while the
low-income tourists tend to decide their travel parties conditional on the
destination choice (latent class 2)
大意是說高收入的旅客傾向根據旅伴決定旅行的目的地
低收入的旅客頃向先決定目的地再決定旅行的同伴
還是是反過來解釋
謝謝
