estimate_QoI takes a dataframe already prepared with split IDs,
plugin estimates and pseudo-outcomes and calculates the requested
quantities of interest (QoIs).
estimate_QoI(data, ...)To see an example analysis, read vignette("experimental_analysis") in the context
of an experiment, vignette("experimental_analysis") for an observational study, or
vignette("methodological_details") for a deeper dive under the hood.
