gfoRmulaICE:Parametric Iterative Conditional Expectation G-Formula
Implements iterative conditional expectation (ICE) estimators of the plug-in g-formula (Wen, Young, Robins, and
Hernán (2020) <doi: 10.1111/biom.13321>). Both singly robust
and doubly robust ICE estimators based on parametric models are
available. The package can be used to estimate survival curves
under sustained treatment strategies (interventions) using
longitudinal data with time-varying treatments, time-varying
confounders, censoring, and competing events. The interventions
can be static or dynamic, and deterministic or stochastic
(including threshold interventions). Both prespecified and
user-defined interventions are available.
