df_uc_om_sel_source

Data with complete information on the three sources of bias, three known
confounders, and 100,000 observations. This data is used to derive
<code>df_uc_om_sel</code> and can be used to obtain bias parameters for purposes
of validating the simultaneous multi-bias adjustment method with
<code>df_uc_om_sel</code>. With this source data, the fitted regression
logit(P(Y=1)) = &alpha;0 + &alpha;1X + &alpha;2C1 + &alpha;3C2 + &alpha;4C3 + &alpha;5U
shows that the true, unbiased exposure-outcome odds ratio = 2.

datasets

Quantify the causal effect of a binary exposure on a binary
outcome with adjustment for multiple biases. The functions can
simultaneously adjust for any combination of uncontrolled confounding,
exposure/outcome misclassification, and selection bias.
The underlying method generalizes the concept of combining inverse
probability of selection weighting with predictive value weighting.
Simultaneous multi-bias analysis can be used to enhance the validity
and transparency of real-world evidence obtained from observational,
longitudinal studies. Based on the work from Paul Brendel, Aracelis Torres,
and Onyebuchi Arah (2023) <doi:10.1093/ije/dyad001>.
