MC HAMMER Monte Carlo Simulation and Business Analysis tools for Julia

Documentation Build Status


The MC in MCHammer stands for Monte-Carlo. This tool is inspired by seminal tools such as Oracle Crystal Ball and Palisade @RISK for their ability to quickly build and analyze Monte-Carlo simulation models using excel functions and automations.

Though you can build a Monte-Carlo simulation in Julia using a few simple packages, it can be tedious setting up all the charts and analysis every time you build a new model. In order to save time and improve clarity, we have taken the standard charts and analysis used in every Monte-Carlo simulation and packaged them into functions that allow the user to focus on modeling instead of coding the same things over and over again.

MCHammer replicates Excel's familiar logic, functions and elemental tools in Julia, thus significantly reducing the time, complexity and effort to perform advanced modeling and simulation.

Why use MCHammer to build your Monte-Carlo simulation model?

  • Ability to correlate variables using Iman-Connover's numeric method with a simple function.
  • Analyze and visualize input data and simulation results using simple Excel like formulas
  • Simplify and eliminate 100s of lines of code for your charts and results analysis using MCHammers wrapper functions.
  • Elegant pre-built chart functions for rendering your simulation results : Histograms, Trend Charts, Sensitivity analysis.
  • Time Series functions to stress test your model over multiple time periods.
  • Easy for an Excel analyst to pick up quickly.

Example models and applications

Project Mission

We want to give access to models to those who need it because for too long insight has inadvertently been hidden away on some analysts computers. This project has the objective to give business analysts tools to either develop or migrate advanced models quickly into Julia so they can be used embedded into systems and workflows that support entire teams and organizations. More people who have access to insights generated by a model, the better the decision making will be over time.

Development Roadmap

  • Functions : MetaLog Distributions
  • Chart: Changes to output means Sensitivity Chart
  • Function: Combined Expert Opinion
  • Time Series: Learning Curve Forecasts
  • Chart: Error Bar Example (base code in mch_charts)
