  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. 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:

  4. Hazard quotient - Wikipedia

    en.wikipedia.org/wiki/Hazard_quotient

    A hazard quotient is the ratio of the potential exposure to a substance and the level at which no adverse effects are expected. If the Hazard Quotient is calculated to be less than 1, then no adverse health effects are expected as a result of exposure. If the Hazard Quotient is greater than 1, then adverse health effects are possible.

  5. Hazard insurance protects against either named perils or open perils, depending on the type of policy. Let’s look at what that means. A named perils policy protects your home against 16 specific ...

  6. Talk:Hazard ratio - Wikipedia

    I think this confusion between hazard ratio and risk ratio is already apparent in the current version of this page: a treatment increasing the number of one-year survivors in a population from one in 10,000 to one in 1,000 has a hazard ratio of 10. This is not true. The relative risk is 10. With the help a statistical software, I found out that ...

    For this example, divide your monthly debt payments ($2,400) by your total monthly gross income ($6,000). In this case, your total DTI would be 0.40, or 40 percent. To confirm your number, use a ...

  9. Accelerated failure time model - Wikipedia

    en.wikipedia.org/wiki/Accelerated_failure_time_model

    In full generality, the accelerated failure time model can be specified as [2] (|) = ()where denotes the joint effect of covariates, typically = ⁡ ([+ +]). (Specifying the regression coefficients with a negative sign implies that high values of the covariates increase the survival time, but this is merely a sign convention; without a negative sign, they increase the hazard.)
