strat

This function identifies the stratifying on treatment history ICE estimator. The classical stratifying on 
treatment history ICE estimator is specified by <code>strat(hazard = FALSE)</code>. The hazard based stratifying on treatment
history ICE estimator is specified by <code>strat(hazard = TRUE)</code>.

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.
