  2. Hazard ratio - Wikipedia

    en.wikipedia.org/wiki/Hazard_ratio

    The hazard ratio is the effect on this hazard rate of a difference, such as group membership (for example, treatment or control, male or female), as estimated by regression models that treat the logarithm of the HR as a function of a baseline hazard () and a linear combination of explanatory variables:

  3. Searching for the right homeowners insurance policy can be confusing. There is insurance-specific terminology to master, for example. One phrase you may hear when you are talking to insurance ...

  4. Proportional hazards model - Wikipedia

    en.wikipedia.org/wiki/Proportional_hazards_model

    For example, the hazard ratio of company 5 to company 2 is ⁡ (()) =. This means that, within the interval of study, company 5's risk of "death" is 0.33 ≈ 1/3 as large as company 2's risk of death. There are important caveats to mention about the interpretation:

  5. Moral hazard - Wikipedia

    en.wikipedia.org/wiki/Moral_hazard

    The individual taking greater risks during the period would be ex-ante moral hazard whereas lying about a fictitious health problem to defraud the insurance company would be ex post moral hazard. A second example is the case of a bank making a loan to an entrepreneur for a risky business venture.

  6. Nelson–Aalen estimator - Wikipedia

    en.wikipedia.org/wiki/Nelson–Aalen_estimator

    The Nelson–Aalen estimator is a non-parametric estimator of the cumulative hazard rate function in case of censored data or incomplete data. [1] It is used in survival theory, reliability engineering and life insurance to estimate the cumulative number of expected events. An "event" can be the failure of a non-repairable component, the death ...

  7. Discrete-time proportional hazards - Wikipedia

    en.wikipedia.org/wiki/Discrete-time_proportional...

    This maximum likelihood maximization depends on the specification of the baseline hazard functions. These specifications include fully parametric models, piece-wise-constant proportional hazard models, or partial likelihood approaches that estimate the baseline hazard as a nuisance function. [4]

  8. Hazard analysis - Wikipedia

    en.wikipedia.org/wiki/Hazard_analysis

    When used as part of an aviation hazard analysis, a "Likelihood" is a specific probability. It is the joint probability of a hazard occurring, that hazard causing or contributing to an aircraft accident or incident, and the resulting degree of loss or harm falling within one of the defined severity categories.

  9. Job safety analysis - Wikipedia

    en.wikipedia.org/wiki/Job_safety_analysis

    The headings of the three basic columns are: Job step, hazard and controls. A hazard is any factor that can cause damage to personnel, property or the environment (some companies include loss of production or downtime in the definition as well). A control is any process for controlling a hazard. The job is broken down into its component steps.
