Summary: | Credible causal effect estimation requires treated subjects and controls to
be otherwise similar. In observational settings, such as analysis of electronic
health records, this is not guaranteed. Investigators must balance background
variables so they are similar in treated and control groups. Common approaches
include matching (grouping individuals into small homogeneous sets) or
weighting (upweighting or downweighting individuals) to create similar
profiles. However, creating identical distributions may be impossible if many
variables are measured, and not all variables are of equal importance to the
outcome. The joint variable importance plot (jointVIP) package to guides
decisions about which variables to prioritize for adjustment by quantifying and
visualizing each variable's relationship to both treatment and outcome. |
