InterUplift function

Interaction estimator

Fit the interaction uplift model estimator.

## S3 method for class 'formula'
InterUplift(formula, treat, data, ...)

## Default S3 method:
InterUplift(data, treat, outcome, predictors, input = "all", ...)

Arguments

• data, formula: a data frame containing the treatment, the outcome and the predictors or a formula describing the model to be fitted.
• treat: name of a binary (numeric) vector representing the treatment assignment (coded as 0/1).
• outcome: name of a binary response (numeric) vector (coded as 0/1).
• predictors: a vector of names representing the explanatory variables to include in the model.
• input: an option for predictors argument. If "all" (default), the model assumes that the model has to create the interaction of all varibles with treat. If "best", the model assumes that the predictors vector is the output of the BestFeatures function.
• ...: additional arguments (other than formula, family, and data) to be passed to glm function for the interaction model.

Returns
