Get all valid adjustment sets in an ADMG — all_adjustment_sets_admg • caugi

Enumerates all valid adjustment sets for estimating the causal effect of X on Y in an ADMG, up to a specified maximum size.

Usage

all_adjustment_sets_admg(
  cg,
  X = NULL,
  Y = NULL,
  X_index = NULL,
  Y_index = NULL,
  minimal = TRUE,
  max_size = 3L
)

Arguments

cg: A caugi object of class ADMG.
X, Y: Node names (can be vectors for multiple treatments/outcomes).
X_index, Y_index: Optional 1-based indices.
minimal: Logical; if TRUE (default), only minimal sets are returned.
max_size: Integer; maximum size of sets to consider (default 3).

Value

A list of character vectors, each a valid adjustment set (possibly empty list if none exist).
