ATbounds (version 0.1.0)

simulation_dgp: Simulating observations from the data-generating process considered in Lee and Weidner (2021)

Description

Simulates observations from the data-generating process considered in Lee and Weidner (2021)

Usage

simulation_dgp(n, ps_spec = "overlap", x_discrete = FALSE)

Arguments

n

sample size

ps_spec

specification of the propensity score: "overlap" or "non-overlap" (default: "overlap")

x_discrete

TRUE if the distribution of the covariate is uniform on -3.0, -2.9, ..., 3.0 and FALSE if the distribution of the covariate is uniform on [--3,3] (default: FALSE)

Value

An S3 object of type "ATbounds". The object has the following elements.

outcome

n observations of binary outcomes

treat

n observations of binary treatments

covariate

n observations of a scalar covariate

ate_oracle

the sample analog of E[Y(1) - Y(0)]

att_oracle

the sample analog of E[DY(1) - Y(0)|D=1]
