  2. Negative probability - Wikipedia

    en.wikipedia.org/wiki/Negative_probability

    Negative probabilities have more recently been applied to mathematical finance.In quantitative finance most probabilities are not real probabilities but pseudo probabilities, often what is known as risk neutral probabilities. [14]

  3. Risk - Wikipedia

    en.wikipedia.org/wiki/Risk

    Firefighters are exposed to risks of fire and building collapse during their work.. In simple terms, risk is the possibility of something bad happening. [1] Risk involves uncertainty about the effects/implications of an activity with respect to something that humans value (such as health, well-being, wealth, property or the environment), often focusing on negative, undesirable consequences. [2]

  4. Risk aversion - Wikipedia

    en.wikipedia.org/wiki/Risk_aversion

    This pattern is an indication of risk-seeking behavior in negative prospects and eliminates other explanations for the certainty effect such as aversion for uncertainty or variability. [ 18 ] The initial findings regarding the reflection effect faced criticism regarding its validity, as it was claimed that there are insufficient evidence to ...

  5. Risk management - Wikipedia

    en.wikipedia.org/wiki/Risk_management

    As a professional role, a risk manager [8] will "oversee the organization's comprehensive insurance and risk management program, assessing and identifying risks that could impede the reputation, safety, security, or financial success of the organization", and then develop plans to minimize and / or mitigate any negative (financial) outcomes.

  6. Risk aversion (psychology) - Wikipedia

    en.wikipedia.org/wiki/Risk_aversion_(psychology)

    Risk aversion is a preference for a sure outcome over a gamble with higher or equal expected value. Conversely, rejection of a sure thing in favor of a gamble of lower or equal expected value is known as risk-seeking behavior.

  7. False positives and false negatives - Wikipedia

    en.wikipedia.org/wiki/False_positives_and_false...

    Complementarily, the false negative rate (FNR) is the proportion of positives which yield negative test outcomes with the test, i.e., the conditional probability of a negative test result given that the condition being looked for is present. In statistical hypothesis testing, this fraction is given the letter β.

  8. Positive and negative predictive values - Wikipedia

    en.wikipedia.org/wiki/Positive_and_negative...

    The negative predictive value is defined as: = + = where a "true negative" is the event that the test makes a negative prediction, and the subject has a negative result under the gold standard, and a "false negative" is the event that the test makes a negative prediction, and the subject has a positive result under the gold standard.

  9. Risk difference - Wikipedia

    en.wikipedia.org/wiki/Risk_difference

    The risk difference (RD), excess risk, or attributable risk [1] is the difference between the risk of an outcome in the exposed group and the unexposed group. It is computed as I e − I u {\displaystyle I_{e}-I_{u}} , where I e {\displaystyle I_{e}} is the incidence in the exposed group, and I u {\displaystyle I_{u}} is the incidence in the ...
