  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:

    The hazard ratio is the ... One example of the use of hazard models with time-varying regressors is estimating the effect of unemployment insurance on unemployment ...

  4. Hazard insurance and dwelling coverage are the same thing. Dwelling insurance is the part of your policy that covers your actual house — from roof to foundation — but not the contents of your ...

  5. Failure rate - Wikipedia

    en.wikipedia.org/wiki/Failure_rate

    A concept closely-related but different [2] to instantaneous failure rate () is the hazard rate (or hazard function), (). In the many-system case, this is defined as the proportional failure rate of the systems still functioning at time t {\displaystyle t} (as opposed to f ( t ) {\displaystyle f(t)} , which is the expressed as a proportion of ...

    Insurance can influence the probability of losses through moral hazard, insurance fraud, and preventive steps by the insurance company. Insurance scholars have typically used moral hazard to refer to the increased loss due to unintentional carelessness and insurance fraud to refer to increased risk due to intentional carelessness or ...

  7. Discrete-time proportional hazards - Wikipedia

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

    This approach performs well for certain measures and can approximate arbitrary hazard functions relatively well, while not imposing stringent computational requirements. [5] When the covariates are omitted from the analysis, the maximum likelihood boils down to the Kaplan-Meier estimator of the survivor function.

  8. Nyman's model - Wikipedia

    en.wikipedia.org/wiki/Nyman's_model

    Moral hazard, the additional healthcare consumed because of insurance, can be decomposed into an efficient (welfare increasing) portion and an inefficient (welfare decreasing) one, based on what the insured patient would have done with the income if they had been written a cashier's check for the insurance spending, instead of the insurer ...

    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.
