During survival analysis it is very useful to compare the hazard rates of two groups of similar attributes within the examined dataset, by employing the hazard ratio (HR). The hazard rate function , also known as the force of mortality or the failure rate, is defined as the ratio of the density function and the survival function.That is, , where is the survival model of a life or a system being studied. The hazard rate (or conditional failure rate) is a metric which is usually used for identifying the appropriate probability distribution of a particular mechanism [71]. It is a rate per unit of time similar in meaning to reading a car speedometer at a particular instant and seeing 45 mph.

Survival Distributions, Hazard Functions, Cumulative Hazards 1.1 De nitions: The goals of this unit are to introduce notation, discuss ways of probabilisti-cally describing the distribution of a ‘survival time’ random variable, apply these to several common parametric families, and discuss how observations of survival times can be right-censored. In survival analysis, the hazard ratio (HR) is the ratio of the hazard rates corresponding to the conditions described by two levels of an explanatory variable. The hazard ratio would be 2, indicating higher hazard of death from the treatment. Hazard Ratio. Hazard rate refers to the rate of death for an item of a given age (x), and is also known as the failure rate. For example, in a drug study, the treated population may die at twice the rate per unit time as the control population. The failure rate is the rate at which the population survivors at any given instant are "falling over the cliff" The failure rate is defined for non repairable populations as the (instantaneous) rate of failure for the survivors to time \(t\) during the next instant of time.

In this definition, is usually taken as a continuous random variable with nonnegative real values as support. MedCalc's free online Relative risk statistical calculator calculates Relative risk and Number needed to treat (NNT) with 95% Confidence Intervals from a 2x2 table.
