get_scores.causal_forest | R Documentation |
Compute doubly robust (AIPW) scores for average treatment effect estimation or average partial effect estimation with continuous treatment, using a causal forest. Under regularity conditions, the average of the DR.scores is an efficient estimate of the average treatment effect.

forest |
A trained causal forest. |
subset |
Specifies subset of the training examples over which we estimate the ATE. WARNING: For valid statistical performance, the subset should be defined only using features Xi, not using the treatment Wi or the outcome Yi. |
debiasing.weights |
A vector of length n (or the subset length) of debiasing weights. If NULL (default) they are obtained via inverse-propensity weighting in the case of binary treatment or by estimating Var[W | X = x] using a new forest in the case of a continuous treatment. |
num.trees.for.weights |
Number of trees used to estimate Var[W | X = x]. Note: this argument is only used when debiasing.weights = NULL. |

Additional arguments (currently ignored). |
A vector of scores.
