AGPC: an Annual 500 m Gridded Population (1990–2020) for China incorporating 3D building volume dynamics

Gridded population datasets with long-term temporal coverage and fine spatial resolution are essential for earth system modelling, urban studies, and disaster risk assessment. However, existing population products often fail to adequately represent population distribution in vert...

Asymptotic FDR Control with Model-X Knockoffs: Is Moments Matching Sufficient?

We propose a unified theoretical framework for studying the robustness of the model-X knockoffs framework by investigating the asymptotic false discovery rate (FDR) control of the practically implemented approximate knockoffs procedure. This procedure deviates from the model-X kn...
