dagR (version 1.1.1)

msas: Identify minimal sufficient adjustment sets.

Description

Evaluates DAG adjustment sets identified by a dag.search (or brute.search) for minimal sufficiency by counting for each sufficient adjustment set A how many smaller sufficient ones that are contained in A exist.

Usage

msas(adjSets)

Arguments

adjSets

The searchRes component of a DAG (or the output of brute.search, which is used by dag.adjust to produce searchRes).

Value

• A vector containing a -1 for each insufficient adjustment set, and for sufficient ones the number of smaller sufficient ones contained in it.
