A per-unit counterfactual law

The return type of gmm_counterfactual(): a discrete law on K atoms (the per-component counterfactual outcomes) with abduction weights, plus the one identified summary – the counterfactual mean. The atom spread is regime (epistemic) uncertainty about which structural component generated the unit; it is not the counterfactual outcome's dispersion, which is unidentified. Accordingly gmm_cf_variance() and gmm_cf_tail_prob() refuse to answer.

Usage

gmm_counterfactual_law(
  atoms = numeric(0),
  weights = numeric(0),
  mean = numeric(0),
  query = integer(0),
  evidence = numeric(0),
  do = numeric(0),
  name = "gmm_counterfactual_law",
  metadata = list()
)

evidence

Numeric vector – the observed unit.
