isAdjustmentSet: Adjustment Criterion
In dagitty: Graphical Analysis of Structural Causal Models

Description Usage Arguments Details References

Test whether a set fulfills the adjustment criterion, that means, it removes all confounding bias when estimating a *total* effect. This is an #' Back-door criterion (Shpitser et al, 2010; van der Zander et al, 2014; Perkovic et al, 2015) which is complete in the sense that either a set fulfills this criterion, or it does not remove all confounding bias.

1	isAdjustmentSet(x, Z, exposure = NULL, outcome = NULL)

`x`	the input graph, a DAG, MAG, PDAG, or PAG.
`Z`	vector of variable names.
`exposure`	name(s) of the exposure variable(s). If not given (default), then the exposure variables are supposed to be defined in the graph itself.
`outcome`	name(s) of the outcome variable(s), also taken from the graph if not given.

If the input graph is a MAG or PAG, then it must not contain any undirected edges (=hidden selection variables).
