Berry-Esseen theorems for the asymptotic normality of incomplete U-statistics with Bernoulli sampling
Dennis Leung
There has been a resurgence of interest in incomplete U-statistics that only sum over a subset of kernel evaluations, due to their computational efficiency and asymptotic normality…
Singularity-agnostic incomplete U-statistics for testing polynomial constraints in Gaussian covariance matrices
Dennis Leung, Nils Sturma
Testing the goodness-of-fit of a model with its defining functional constraints in the parameters could date back to Spearman (1927), who analyzed the famous "tetrad" polynomial in…
Algebraic tests of general Gaussian latent tree models
Dennis Leung, Mathias Drton
We consider general Gaussian latent tree models in which the observed variables are not restricted to be leaves of the tree. Extending related recent work, we give a full semi-alge…
Identifiability of directed Gaussian graphical models with one latent source
Dennis Leung, Mathias Drton, Hisayuki Hara
We study parameter identifiability of directed Gaussian graphical models with one latent variable. In the scenario we consider, the latent variable is a confounder that forms a sou…
