Concept guide

Sensitivity

Also used: sensitivity analysis · numerical sensitivity

How a chosen output or conclusion changes when specified inputs or settings change. Global sensitivity analysis can attribute output uncertainty to uncertain inputs.

An example from the writing

The folding study refines numerical integration to check whether computed coefficients, energies and events change.

A common misconception

Stability under one small change establishes insensitivity everywhere.

That inference does not follow. Read the result together with its scope below.

Scope and limits

This example is a numerical sensitivity check, not a global variance decomposition. Agreement on known roots does not enumerate unknown branches.

  • How Many Equilibria Did the Optimizer Miss?

    A folding-energy study separates minima from saddles, global energy ordering from metastability, and branch discovery from proof, asking when an optimizer's attractive shape map leaves something important out.

  • What Must a Traffic Model Remember?

    A controlled ring-road study separates hidden velocity, projection-induced memory, noisy observation, and numerical sensitivity, asking when a better traffic forecast also gives a better stability diagnosis.

  • When Solar Power Changes Fast: Why Better Intervals Are Still Not Reliable Enough

    A five-station study asks whether solar prediction intervals remain trustworthy during rapid power changes and missing sensor inputs. Better calibration improves every station, yet the hardest groups still fall far below the intended coverage.
