The conditional permutation test for independence while controlling for confounders

Journal of the Royal Statistical Society: Series B (Statistical Methodology), Volume 82, Issue 1, Page 175-197, February 2020., 2020
Summary We propose a general new method, the conditional permutation test, for testing the conditional independence of variables X and Y given a potentially high dimensional random vector Z that may contain confounding factors. The test permutes entries of X non‐uniformly, to respect the existing dependence between X and Z and thus to account for the ...

Representations of urban cycling in sustainability transitions research: a review

European Transport Research Review, 2023
Background Increased cycling is generally recognized as a highly important project in decarbonizing urban transport. Despite well-researched and broadly accepted benefits of cycling, bicycle mobility plays only a marginal role in the modal share for most

Machine Learning Approach to Quantity Management for Long‐Term Sustainable Development of Dockless Public Bike: Case of Shenzhen in China

Journal of Advanced Transportation, Volume 2020, Issue 1, 2020., 2020
Since the number of bicycles is critical to the sustainable development of dockless PBS, this research practiced the introduction of a machine learning approach to quantity management using OFO bike operation data in Shenzhen. First, two clustering algorithms were used to identify the bicycle gathering area, and the available bike number and ...

Residents in Seattle, WA Report Differential Use of Free-Floating Bikeshare by Age, Gender, Race, and Location

Frontiers in Built Environment, 2019
Bikesharing may have numerous urban health, sustainability, and mobility benefits. Bikesharing systems that do not require stations (i.e., “dockless,” or “free-floating” bikeshare) launched in North America in 2017.

Digital twins and deep maps

Transactions of the Institute of British Geographers, Volume 50, Issue 1, March 2025.
Short Abstract We reflect on our work to produce a 3D city information model (CIM) for Dublin that acts as a basic digital twin, and our initial attempt to use the CIM to create a deep map. We consider the politics of creating digital twins and deep maps and what they mean for how we understand the nature of mapping, arguing that they produce a dyadic ...
