  2. Risk matrix - Wikipedia

    en.wikipedia.org/wiki/Risk_matrix

    Risk is the lack of certainty about the outcome of making a particular choice. Statistically, the level of downside risk can be calculated as the product of the probability that harm occurs (e.g., that an accident happens) multiplied by the severity of that harm (i.e., the average amount of harm or more conservatively the maximum credible amount of harm).

  3. Population viability analysis - Wikipedia

    en.wikipedia.org/wiki/Population_viability_analysis

    Population viability analysis (PVA) is a species-specific method of risk assessment frequently used in conservation biology.It is traditionally defined as the process that determines the probability that a population will go extinct within a given number of years.

  4. Probabilistic risk assessment - Wikipedia

    en.wikipedia.org/wiki/Probabilistic_risk_assessment

    Such external events may be natural hazard, including earth quake and tsunami, fire, and terrorist attacks, and are treated as a probabilistic argument. [2] Changing historical context shall condition the probability of those events, e.g. a nuclear program or economic sanctions.

  5. Population impact measure - Wikipedia

    en.wikipedia.org/wiki/Population_impact_measure

    To describe the impact of preventive and treatment interventions, the number of events prevented in a population (NEPP) is defined as "the number of events prevented by the intervention in a population over a defined time period". NEPP extends the well-known measure number needed to treat (NNT) beyond the individual patient to the population.

  6. Risk assessment - Wikipedia

    en.wikipedia.org/wiki/Risk_assessment

    Risk assessment determines possible mishaps, their likelihood and consequences, and the tolerances for such events. [1] The results of this process may be expressed in a quantitative or qualitative fashion. Risk assessment is an inherent part of a broader risk management strategy to help reduce any potential risk-related consequences. [1] [2]

  7. Statistical risk - Wikipedia

    en.wikipedia.org/wiki/Statistical_risk

    Statistical risk is a quantification of a situation's risk using statistical methods.These methods can be used to estimate a probability distribution for the outcome of a specific variable, or at least one or more key parameters of that distribution, and from that estimated distribution a risk function can be used to obtain a single non-negative number representing a particular conception of ...

  8. Risk management - Wikipedia

    en.wikipedia.org/wiki/Risk_management

    Example of risk assessment: A NASA model showing areas at high risk from impact for the International Space Station. Risk management is the identification, evaluation, and prioritization of risks, [1] followed by the minimization, monitoring, and control of the impact or probability of those risks occurring. [2]

  9. Qualitative risk analysis - Wikipedia

    en.wikipedia.org/wiki/Qualitative_Risk_Analysis

    Qualitative risk analysis is a technique used to quantify risk associated with a particular hazard. Risk assessment is used for uncertain events that could have many outcomes and for which there could be significant consequences. Risk is a function of probability of an event (a particular hazard occurring) and the consequences given the event ...
