Mixed-mode surveys, in which different respondents complete the survey by different modes, become increasingly popular. That said, such surveys may lead to a confounding of two forms of mode effects, ...

But not all copulas are created equal. Normal mean-variance mixture copulas can capture heavy tails and asymmetries in the ...

Abstract: In the era of massive data, how to obtain valuable information from large-scale data has become an important research direction. Subsampling is a common method to reduce the dimension of ...

Abstract: Travel demand management (TDM) strategies have been widely adopted to tackle the persisting traffic congestion in metropolitan areas [1]. To evaluate the effects of TDM strategies, it is ...

The distribution of an arbitrary linear combination of Student-t random variables with odd degrees of freedom is derived. An easy method of expressing this distribution as a mixture of t-distributions ...

Background Sudden cardiac death (SCD) is a common cause of cardiovascular mortality, often triggered by ventricular ...

This study addresses an important question and shows how social navigation in homing pigeons can be explained by simple averaging, without requiring any complex cognitive abilities. The evidence, ...
