Estimating and Controlling the False Discovery Rate for the PC Algorithm Using Edge-Specific P-Values

1 code implementation14 Jul 2016 Eric V. Strobl, Peter L. Spirtes, Shyam Visweswaran

The PC algorithm allows investigators to estimate a complete partially directed acyclic graph (CPDAG) from a finite dataset, but few groups have investigated strategies for estimating and controlling the false discovery rate (FDR) of the edges in the CPDAG.

Calculation of Entailed Rank Constraints in Partially Non-Linear and Cyclic Models

no code implementations17 Sep 2013 Peter L. Spirtes

The Trek Separation Theorem (Sullivant et al. 2010) states necessary and sufficient conditions for a linear directed acyclic graphical model to entail for all possible values of its linear coefficients that the rank of various sub-matrices of the covariance matrix is less than or equal to n, for any given n. In this paper, I extend the Trek Separation Theorem in two ways: I prove that the same necessary and sufficient conditions apply even when the generating model is partially non-linear and contains some cycles.
