Value

An object of itr class

Arguments

treatment: Treatment variable
form: a formula object that takes the form y ~ T + x1 + x2 + ....
data: A data frame that contains the outcome y and the treatment T.
algorithms: List of machine learning algorithms to be used.
budget: The maximum percentage of population that can be treated under the budget constraint.
n_folds: Number of cross-validation folds. Default is 5.
split_ratio: Split ratio between train and test set under sample splitting. Default is 0.
ngates: The number of groups to separate the data into. The groups are determined by tau. Default is 5.
preProcess: caret parameter
weights: caret parameter
trControl: caret parameter
tuneGrid: caret parameter
tuneLength: caret parameter
user_model: A user-defined function to create an ITR. The function should take the data as input and return a model to estimate the ITR.
SL_library: A list of machine learning algorithms to be used in the super learner.
...: Additional arguments passed to caret::train
