Expanded dataset including either ratio-of-mediator probability weights or imputed nested counterfactual outcomes.
A data frame, resulting from applying neWeight or neImpute on an original dataset data.
This data frame has nRep * length(data) rows, containing all original variables (except the original exposure variable)
and two variables reflecting observed and hypothetical values of the exposure for each observation unit.
These auxiliary variables (x and x*) are named after the exposure variable and carry integers as suffixes.
Suffixes 0 and 1 are used for variables whose corresponding parameters in the final natural effect model index natural direct and indirect effects, respectively.
This object also stores some additional attributes, which are used as input for neModel, such as
