SEMID: Identifiability of Linear Structural Equation Models

Share:

Provides routines to check identifiability or non-identifiability of linear structural equation models as described in Drton, Foygel & Sullivant (Ann. Statist., 2011) and Foygel, Draisma & Drton (Ann. Statist., 2012). The routines are based on the graphical representation of structural equation models by a path diagram/mixed graph.
