Simulated Dataset for Normal Outcome
Description
A dataset generated for illustration of the principal stratification analysis. This dataset represents the common case of non-compliance.
Usage
sim_data_normal
Format
## 'sim_data_normal' A data frame with 1,000 rows and 4 columns:
- S
Principal Strata: "never taker", "complier" or "always taker"
- Z
Randomized treatment arm: 0 = control, 1 = treatment
- D
Actual treatment arm: 0 = control, 1 = treatment
- Y
Outcome
Details
The dataset represents the scenario where actual treatment might not be in compliance
with the randomized (assigned) treatment. Defiers are ruled out, leaving three
strata, "never taker", "complier" and "always taker" randomly sampled with
probability 0.3, 0.2 and 0.5 respectively. The assigned treatment Z is randomized
with 0.5 probability for either arm. The outcome Y is given by the following.
- never taker
Y \sim N(3, 1)- complier
Y \sim N(-1-Z, 0.5)- always taker
Y \sim N(1, 2)
The exclusion restriction assumption holds for never takers and always takers in this generated dataset.
