Rescuing double robustness: safe estimation under complete misspecification

Lorenzo Testa, Francesca Chiaromonte, Kathryn Roeder

Double robustness is a major selling point of semiparametric and missing data methodology. Its virtues lie in protection against partial nuisance misspecification and asymptotic se…

Semiparametric semi-supervised learning for general targets under distribution shift and decaying overlap

Lorenzo Testa, Qi Xu, Jing Lei +1

In modern scientific applications, large volumes of covariate data are readily available, while outcome labels are costly, sparse, and often subject to distribution shift. This asy…

A unified repository for pre-processed climate data weighted by gridded economic activity

Marco Gortan, Lorenzo Testa, Giorgio Fagiolo +1

Although high-resolution gridded climate variables are provided by multiple sources, the need for country and region-specific climate data weighted by indicators of economic activi…
