- Normal distribution fitting
- Lognormal distribution for positive values
- Triangular distribution for expert estimates
- PERT distribution modeling
- Custom distribution creation
- Historical data-based fitting
Correlation Matrix Handling
- Variable correlation specification
- Cholesky decomposition for correlated sampling
- Copula implementation
- Rank correlation (Spearman)
- Correlation stability testing
- Partial correlation analysis
Convergence Analysis
- Sample size determination
- Convergence testing
- Precision metrics calculation
- Stopping criteria implementation
- Result stability verification
- Computational efficiency optimization
Value at Risk (VaR) Calculation
- Parametric VaR
- Historical simulation VaR
- Monte Carlo VaR
- Expected shortfall (CVaR)
- Marginal VaR
- Incremental VaR
Confidence Interval Generation
- Percentile-based intervals
- Bootstrap confidence intervals
- Prediction intervals
- Tolerance intervals
- One-sided bounds
- Joint confidence regions
Crystal Ball/ModelRisk Integration
- @RISK compatibility
- Crystal Ball formula support
- Model export capabilities
- Simulation result import
- Assumption synchronization
- Report generation
Usage
Risk Quantification
Input: Key uncertain variables, probability distributions, correlations
Process: Run simulations, aggregate results, calculate risk metrics
Output: Probability distributions of outcomes, VaR, confidence intervals
Scenario Probability
Input: Model structure, variable ranges, target outcomes
Process: Simulate scenarios, identify conditions for targets
Output: Probability of achieving targets, key driver sensitivity
Integration
Used By Processes
