Sensitivity analysis is a systematic methodology for quantifying how uncertainty in model inputs propagates to uncertainty in model outputs. Parameters: (1) a formal model or simulation with definable input-output mapping; (2) a specified range or distribution for each input parameter; (3) a sampling strategy (local perturbation, global variance-decomposition, or Morris screening) to explore the input space; (4) output metrics (variance, elasticity, or Sobol indices) to measure influence. Persistence mechanism: mathematical formalization in statistics and computational mathematics, institutionalized through software toolkits (SALib, UQpy), regulatory guidance in engineering and environmental science, and peer-reviewed methodology literature.

Definition
Why it is in scope
A human-made analytical methodology: a systematic procedure for measuring how variations in input parameters affect the output of a model, simulation, or system. Built to persist through mathematical formalization, computational implementation, and cross-disciplinary practice in science, engineering, and policy analysis.

Sensitivity-analysis IS a specific kind of methodology — a systematic procedure for quantifying how input variation affects output. A competent speaker says 'sensitivity analysis is a methodology.' Direction: specific→general per Law 9. Methodology is the nearest kind (epoch 0.04 vs 0.41).

A sensitivity analysis IS a kind of analysis. It is a specific analytical method that determines how different values of an independent variable affect a dependent variable under a given set of assumptions. Law 9: a competent speaker would call a sensitivity analysis 'an analysis.' Nearest kind: analysis.

A sensitivity plot visualizes how model outputs change as inputs vary — its designed purpose is to support sensitivity analysis by revealing which inputs dominate output variance. Servant (plot) → master (analysis). Law 8d.
