High dimensional consistent independence testing with maxima of rank correlations
Mathias Drton, Fang Han, Hongjian Shi
Testing mutual independence for high-dimensional observations is a fundamental statistical challenge. Popular tests based on linear and simple rank correlations are known to be inc…

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…

The Maximum Likelihood Threshold of a Path Diagram
Mathias Drton, Christopher Fox, Andreas Käufl +1
Linear structural equation models postulate noisy linear relationships between variables of interest. Each model corresponds to a path diagram, which is a mixed graph with directed…
