Sharing economy-based accommodations has grown dramatically worldwide. Given the crucial role of pricing, academics have used hedonic methods to estimate a large number implicit prices and accommodation characteristics. It is now time question our estimation methods. Based on methodological literature, this article outlines five proposals improve model performance: extended specification attrib...

Extensions of the traditional Cox proportional hazard model, concerning the following features are often desirable in applications: Simultaneous nonparametric estimation of baseline hazard and usual fixed covariate effects, modelling and detection of time–varying covariate effects and nonlinear functional forms of metrical covariates, and inclusion of frailty components. In this paper, we devel...

In this paper we investigate the use of description length principles to select an appropriate number of basis functions for functional data. We provide a flexible definition of the dimension of a random function that is constructed directly from the Karhunen–Loève expansion of the observed process. Our results show that although the classical, principle component variance decomposition techniq...

abstract researches of preservation valuation of natural resources and environment were done in order to create necessary awareness for making optimal decisions in the field of the ways of economic management of these resources and helping to establish sustainable regional development strategy. in this study, preservation value of lilium ledebourii estimated using single bounded dichotomous cho...

In this paper we propose hinging hyperplanes (HHs) as a flexible nonparametric representation of concave or an S-shaped production function. We derive the HHs using expressions with focus on distinction between hinge location and bending along each hinge. argue that approximation can be estimated fixed endogenous determined partitioning input space. Assuming homothetic function allows us to sep...

Building waste is a critical issue in current construction. Innovative design strategies are required to reduce the depletion of valuable materials and resources through providing flexible and versatile structures. This study focuses on the development of an industrial, flexible, and demountable wall panel construction system. The panel system consists of concrete blocks with steel connectors t...
