The AIM of this study is to examine and evaluate differences in expenditure and length of stay between tourists who use low-cost carriers and those who travel with full service providers. We consider the statistical dependence between these variables and propose a bivariate distribution that describes tourist expenditure (continuous variable) and length of stay (discrete variable) in terms of their conditional distributions. Covariates are included to reflect the factors that simultaneously affect both variables. In addition, an empirical analysis is made of data obtained by the Canary Islands Tourist Expenditure Survey. The results obtained show that our model achieves a reasonably good fit and that there are differences between LCC and FSC users regarding both expenditure and length of stay, in the use of nonhotel accommodation, as well as differences in expenditure in the case of repeated visits, and in the length of stay according to the visitors’ age, nationality and travel party size.

本研究的目的是检查和评估使用低成本航空公司的游客与使用全方位服务提供商旅行的游客在支出和逗留时间方面的差异。我们考虑了这些变量之间的统计相关性，并提出了一个二元分布，根据它们的条件分布来描述旅游支出（连续变量）和逗留时间（离散变量）。包含协变量以反映同时影响两个变量的因素。此外，对加那利群岛旅游支出调查获得的数据进行了实证分析。获得的结果表明，我们的模型实现了相当好的拟合，并且 LCC 和 FSC 用户在使用非酒店住宿方面的支出和逗留时间方面存在差异，
