**Simulation decomposition** or **SimDec** is an uncertainty and sensitivity
analysis method, which is based on Monte Carlo simulation. SimDec consists of
three major parts:

1. computing sensitivity indices,
2. creating multi-variable scenarios and mapping the output values to them, and
3. visualizing the scenarios on the output distribution by color-coding its segments.

SimDec reveals the nature of causalities and interaction effects in the model.

## Citations

The algorithms and visualizations used in this package came primarily out of
research at LUT University, Lappeenranta, Finland, and Stanford University,
California, U.S., supported with grants from Business Finland, Wihuri
Foundation, and Finnish Foundation for Economic Education.
