isSibling

isSibling.MixedGraph

Provides routines to check identifiability or non-identifiability
of linear structural equation models as described in Drton, Foygel, and
Sullivant (2011) <doi:10.1214/10-AOS859>, Foygel, Draisma, and Drton (2012)
<doi:10.1214/12-AOS1012>, and other works. The routines are based on the graphical
representation of structural equation models.
