# Simulation

- [MCNORM](https://excelhelp.windhamlabs.com/functions/simulation/mcnorm.md): Simulate a matrix of multivariate normal returns using Monte-Carlo with the option to preserve an expected correlation structure.
- [BOOTSTRAP](https://excelhelp.windhamlabs.com/functions/simulation/bootstrap.md): Simulate values by bootstrap sampling from a dateset. The bootstrap method allows for a uniform random sampling, or a biased (probability-weighted) sampling method, useful for scenario analysis.
