Powerful Partial Conjunction Hypothesis Testing via Conditioning
Biyonka Liang, Lu Zhang, Lucas Janson
A Partial Conjunction Hypothesis (PCH) test combines information across a set of base hypotheses to determine whether some subset is non-null. PCH tests arise in a diverse array of…
StarTrek: Combinatorial Variable Selection with False Discovery Rate Control
Lu Zhang, Junwei Lu
Variable selection on the large-scale networks has been extensively studied in the literature. While most of the existing methods are limited to the local functionals especially th…
Pathfinder: Parallel quasi-Newton variational inference
Lu Zhang, Bob Carpenter, Andrew Gelman +1
We propose Pathfinder, a variational method for approximately sampling from differentiable log densities. Starting from a random initialization, Pathfinder locates normal approxima…
Floodgate: inference for model-free variable importance
Lu Zhang, Lucas Janson
Many modern applications seek to understand the relationship between an outcome variable and a covariate in the presence of a (possibly high-dimensional) confounding variab…
