What is incidence rate in statistics

incidence rate the risk of developing a particular disease during a given period of time; the numerator of the rate is the number of new cases during the specified time period and the denominator is the population at risk during the period. The incidence rate is a measure of the frequency with which a disease or other incident occurs over a specified time period. In the same example as above, the incidence rate is 14 cases per 1000 person-years, because the incidence proportion (28 per 1,000) is divided by the number of years (two).

Obviously, prevalence will continue to grow until mortality equals or exceeds the incidence rate. An example of this relationship is shown below. The disease incidence is 100 per year. Mortality rate is 20% per year. As seen, prevalence grows until the death rate equals the incidence. incidence rate the risk of developing a particular disease during a given period of time; the numerator of the rate is the number of new cases during the specified time period and the denominator is the population at risk during the period.

Incidence, in statistics, is the rate of occurrence of something or the number of times it occurs within a population at a particular time or time period. The rate of incidence is usually expressed as a fraction, for example, 48 cases of measles out of a population of 750 schoolchildren over the course of a winter. Obviously, prevalence will continue to grow until mortality equals or exceeds the incidence rate. An example of this relationship is shown below. The disease incidence is 100 per year. Mortality rate is 20% per year. As seen, prevalence grows until the death rate equals the incidence. incidence rate the risk of developing a particular disease during a given period of time; the numerator of the rate is the number of new cases during the specified time period and the denominator is the population at risk during the period. The incidence rate is a measure of the frequency with which a disease or other incident occurs over a specified time period. In the same example as above, the incidence rate is 14 cases per 1000 person-years, because the incidence proportion (28 per 1,000) is divided by the number of years (two). A rate ratio (sometimes called an incidence density ratio) is a measure of association that compares the incidence of events happening at different times. It is used extensively in epidemiology. The formula is the ratio of exposed groups to unexposed groups: Rate ratio = IR e / IR u The incidence rate ratio for a binary predictor variable is simply the ratio of the number of events of one category to the number of events in the other category. For a categorical variable with more than two categories, the IRR is the ratio of the expressed category to the base category.
