What probability and statistics does here.

Probability and statistics provide the mathematical framework for describing uncertainty and learning from data. They underpin estimation, testing and prediction in every risk discipline. In health and biosecurity and food and agriculture, statistical methods quantify the likelihood and uncertainty of losses across interconnected sistem. They make the evidence behind risk decisions explicit and reproducible. The canonical description is on STEM Commons.

SEIR pada jaringan tempat.

An outbreak seeded in one place spreads through a small-world network by the share of contacts people make elsewhere; play it to see the order of arrival and how the timing of measures moves the peak. Teaching model with stated illustrative values, not a prediction.

06Validasi

Cara hasil diperiksa.

Results are checked through diagnostics, cross-validation and sensitivity to assumptions. Independent replication confirms findings.

Inference depends on assumptions about independence, distribution and sampling that may not hold. Small or biased samples limit reliability.
