hesim is an R package for health economic simulation modeling and decision analysis and a part of the Innovation and Value Innitiative’s Open Source Value Project (OSVP). More infromation about hesim can be found on the package website.

hesim interacts wih 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.
