New research proposes horseshoe prior for robust spatial small area estimation

By PulseAugur Editorial · [1 sources] ·

A new paper introduces the horseshoe prior as a robust and effective method for small area estimation, particularly in spatial contexts. The research details a tail-robustness theorem showing the horseshoe model can bound the influence of outlying direct estimates, unlike Gaussian models. It also provides theoretical and empirical evidence on when global-local shrinkage or structured smoothing is more advantageous, concluding that the horseshoe prior is a sound default choice for area effects due to its aggressive borrowing of strength while allowing exceptional areas to be identified.

    Horseshoe Priors for Spatial Small Area Estimation: Regular Variation, Tail Robustness, and Deep Learning

    arXiv:2606.30659v1 Announce Type: cross Abstract: Small area estimation borrows strength across domains to repair the poor precision of direct survey estimators. Two philosophies dominate the area-level literature. The first, descending from Ghosh and Rao (1994), borrows strength…
