View source: R/htcID.R

Description

Uses the half-trek criterion of Foygel, Draisma, and Drton (2012) determine which edges in a mixed graph are generically identifiable. Depending on your application it faster to use the graphID.htcID function instead of this one, this function has the advantage of returning additional information.

Usage

1
htcID(mixedGraph, tianDecompose = T)

Arguments

mixedGraph

a MixedGraph object representing the L-SEM.

tianDecompose

TRUE or FALSE determining whether or not the Tian decomposition should be used before running the current generic identification algorithm. In general letting this be TRUE will make the algorithm faster and more powerful.

Value

see the return value of generalGenericID.
