Issue #200 Analysis: Sensitivity Analysis Already Implemented

[Copilot]

Summary

After thorough analysis of issue #200 "Sensitivity Analysis on Monte Carlo Simulations", I found that this feature has already been fully implemented and the issue was properly closed on September 8, 2024 via PR #575.

Current Implementation Status

The RocketPy repository already contains a comprehensive sensitivity analysis implementation:

Core Implementation

• SensitivityModel class in rocketpy.sensitivity.sensitivity_model.py
• Local variance-based first-order sensitivity analysis using multiple linear regression
• Sensitivity coefficients showing relative parameter importance
• Linear Approximation Error (LAE) for model validation

Documentation & Examples

• Complete user guide in docs/user/sensitivity.rst
• Technical documentation in docs/technical/sensitivity.rst
• Working example in docs/notebooks/monte_carlo_analysis/monte_carlo_sensitivity_simulation.py
• Full test coverage in tests/unit/test_sensitivity.py

Integration

• Properly imported in main package via rocketpy.__init__.py
• Integrated with Monte Carlo simulation workflows
• Plotting and printing capabilities via _SensitivityModelPlots and _SensitivityModelPrints

Key Features Available

The implemented solution provides the exact functionality requested in issue #200:

1. Parameter importance analysis - identifies which parameters most affect flight variables
2. Variance decomposition - shows how much each parameter contributes to output uncertainty
3. Integration with Monte Carlo - works seamlessly with existing MonteCarlo class
4. Statistical validation - includes LAE measure to assess linear approximation quality

Conclusion

Issue #200 has been successfully resolved. The sensitivity analysis feature is production-ready and addresses all requirements specified in the original issue. No additional implementation is needed.

If there are specific aspects of sensitivity analysis that still need enhancement, a new issue should be opened with clear requirements for the additional functionality desired.
