What this category covers
Estimation and hypothesis-testing tools used to judge whether quantitative evidence is stable or accidental. Each concept page explains the quantitative meaning, how the idea is used in portfolio or market analysis, the relevant formula or analytical framework, variables, a compact example and the main limitations to keep in view.
