hesim is an R package for health economic simulation modeling and decision analysis. More information about hesim can be found on the package website.

hesim interacts with the iviRA package in two ways.

1. hesim can be used to analyze simulation output produced by the IVI-RA model (e.g., (individualized) cost-effectiveness analysis).

2. The IVI-RA model uses R code from hesim to sample parameters from the probabilistic sensitivity analysis and C++ code from hesim in the individual patient simulation.
