What is @RISK?

@RISK is an add-in for Microsoft Excel developed by Palisade Corporation used for risk analysis and Monte Carlo simulation. It allows users to define uncertainty in spreadsheet models to gain a better understanding of the risks and probabilities associated with different outcomes.

Some key features of @RISK include:

• Monte Carlo simulation - @RISK runs thousands of "what-if" scenario simulations to show the likelihood and impact of different outcomes
• Risk analysis - Users can define probability distributions for uncertain inputs to quantify risk exposure or opportunity
• Sensitivity analysis - Identifies which inputs are driving uncertainty and risk in the model
• Optimization - Finds combinations of inputs that achieve the best possible outcome
• Forecasting - Models can incorporate uncertainty to generate risk-adjusted forecasts
• Decision trees - Supports building tree diagrams to evaluate choices under uncertain conditions

@RISK integrates seamlessly with Excel, using native Excel formula inputs and outputs while adding risk analysis capabilities not found in standard Excel. It produces interactive summary graphs and reports for risk analysis and is widely used across finance, engineering, manufacturing, and other industries for quantitative risk modeling.
