What is Sensitivity Analysis? - Corporate Finance Institute

WebSep 4, 2024 · Sensitivity Analysis Techniques. The mathematical tools for sensitivity analysis are well-known and can generally be divided into two classes: deterministic and probabilistic. Despite the fact that we are talking about random variations, deterministic techniques only consider a specific value of variation and calculate the system’s output. WebDescription A collection of functions for sensitivity analysis of model outputs (factor screen-ing, global sensitivity analysis and robustness analysis), as well as for interpretability of ma-chine learning models. Most of the functions have to be applied on scalar output, but sev-eral functions support multi-dimensional outputs. License GPL-2
