df_uc {multibias}

Simulated data with uncontrolled confounding

Description

Data containing one source of bias, three known confounders, and 100,000 observations. This data is obtained from df_uc_source by removing the column U. The resulting data corresponds to what a researcher would see in the real-world: information on known confounders (C1, C2, and C3), but nothing for confounder U. As seen in df_uc_source, the true, unbiased exposure-outcome odds ratio = 2.

Usage
