df_uc_sel {multibias} | R Documentation |
Simulated data with uncontrolled confounding and selection bias
Description
Data containing two sources of bias, three known confounders, and 100,000
observations. This data is obtained by sampling with replacement with
probability = S from df_uc_sel_source
then removing the columns
U and S. The resulting data corresponds to what a researcher would see
in the real-world: missing data on confounder U; and missing data for
those not selected into the study (S=0). As seen in
df_uc_sel_source
, the true, unbiased exposure-outcome odds ratio = 2.
Usage
df_uc_sel
Format
A dataframe with 100,000 rows and 3 columns:
- X
exposure, 1 = present and 0 = absent
- Y
outcome, 1 = present and 0 = absent
- C1
1st confounder, 1 = present and 0 = absent
- C2
2nd confounder, 1 = present and 0 = absent
- C3
3rd confounder, 1 = present and 0 = absent
