A companion to SyntheticData with unequal group sizes, for tests and examples where balanced data would hide an error. With equal arms, for example, exchanging the randomization probability and its complement gives the same numbers.

Usage

data(SyntheticDataII)

Format

A data frame with 380 rows and the same 12 columns as SyntheticData: 160 trial patients on treatment (S = 1, A = 1), 80 trial controls (S = 1, A = 0), and 140 external controls (S = 0, A = 0). The trial randomizes 2:1, so the probability of treatment is 2/3. SMA type III (x1 = 1) is more common in the trial than in the external controls. The participation model has good overlap. The outcome models are the same as in SyntheticData, and T_cross is 2 for all rows.

Source

Simulated with simulate_trial(). The script is data-raw/SyntheticDataII.R in the package source on GitHub.
