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)
大意是说高收入的旅客倾向根据旅伴决定旅行的目的地
低收入的旅客顷向先决定目的地再决定旅行的同伴
还是是反过来解释
谢谢
