potential_outcomes: Build potential outcomes variables

Description

Function to draw multiple potential outcomes, one for each condition that an assignment variable can be set to.

Usage

potential_outcomes(x, conditions = list(Z = c(0, 1)), sep = "_")

Arguments

x

Formula describing the potential outcomes with the outcome name on the left hand side and the expression describing the potential outcomes on the right hand side, e.g. Y ~ 0.1 * Z + rnorm(N) (this would draw two potential outcomes columns by default, named Y_Z_0 and Y_Z_1).

conditions

A list of conditions for each assignment variable. Defaults to list(Z = c(0, 1)).

sep

Separator inserted between the outcome name and the assignment variable name used to construct the potential outcome variable names, defaults to "_".

Examples

fabricate(
  N = 10,
  U = rnorm(N),
  potential_outcomes(Y ~ 0.1 * Z + U)
)

# equivalently,

fabricate(
  N = 10,
  U = rnorm(N),
  potential_outcomes(Y ~ 0.1 * Z + U,
                     conditions = list(Z = c(0, 1)))
)

fabricate(
  N = 10,
  U = rnorm(N),
  potential_outcomes(Y ~ 0.1 * Z + U,
                     conditions = list(Z = c(1, 2, 3)))
)

fabricate(
  N = 10,
  U = rnorm(N),
  potential_outcomes(Y ~ 0.1 * Z1 + 0.3 * Z2 + 0.5 * Z1 * Z2 + U,
                     conditions = list(Z1 = c(0, 1),
                                       Z2 = c(0, 1)))
)
