Transform SCC to DAG
Description
Creates an object of class dagitty (dagitty package) from a SCC model, following VanderWeele and Robins (2007).
Usage
scc_to_dag(scc, unknown = TRUE)
Arguments
scc |
An object of class |
unknown |
TRUE (default) or FALSE. If TRUE, unknown causes are added to the SCC model: every sufficient cause gets an additional individual unknown component cause representing additional unknown components; an unknown sufficient cause is added to the model consisting of a single unknown component cause and representing all unknown sufficient causes. |
Value
A list of length 2 containing an object of class dagitty (named dag) and a data.frame containing the information, which label in the
DAG corresponds to which component cause (named legend).
