Simple Additive Modified Treatment Policy

Simple Additive Modified Treatment Policy

shift_additive(a, w = NULL, delta, lower_bound, upper_bound)

Arguments

a

A numeric vector of observed treatment values.

w

A numeric matrix of observed baseline covariate values.

delta

A numeric indicating the magnitude of the shift to be computed for the treatment A.

lower_bound

Lower bound of expossure

upper_bound

Upper bound of exposure

Value

A numeric vector containing the shifted exposure values.

Details

A simple modified treatment policy that modifes the observed value of the exposure by shifting it by a value delta. Note that this shifting function assumes support of A|W across all strata of W.
