This function estimates the Population Average Prescription Effect with and without a budget constraint. The details of the methods for this design are given in Imai and Li (2019).
PAPE(T, That, Y, plim = NA)
The unit-level binary treatment receipt variable.
The unit-level binary treatment that would have been assigned by the individualized treatment rule.
The outcome variable of interest.
The maximum percentage of population that can be treated under the budget constraint. Should be a decimal between 0 and 1. Default is NA which assumes no budget constraint.
A list that contains the following items:
The estimated Population Average Prescription Effect.
The estimated standard deviation of PAPE.
