example for cumulative incidence(Risk)...... Number of new cases/Population at risk 28 patient in two years/1000 person at risk which means 2.8%
the IR for the same example 14 patient / 1 year
Incidence rates vary between 25 and 50 per 100,000 persons.
There is no difference between them they are same rate constant is another name of specific rate constant
Relative risk (RR) can be calculated by comparing the incidence rates of an event occurring in two groups. First, determine the incidence rate in the exposed group (e.g., those with a risk factor) and the incidence rate in the unexposed group (e.g., those without the risk factor). Then, divide the incidence rate of the exposed group by the incidence rate of the unexposed group (RR = Incidence Rate in Exposed / Incidence Rate in Unexposed). A RR greater than 1 indicates increased risk, while a RR less than 1 indicates decreased risk.
mortality rate - death rate
prevalencerefers to the number of cases of disease thatexistsin a population and the incidence refers to the number of new cases of diseaseoccurringin a population.
RD=Re-Ru Rate Difference=Rate of exposed group-Rate of unexposed group.
Cumulative incidence is a measure of frequency, as in epidemiology where it is a measure of disease frequency during a period of time. Cumulative incidence is the incidence calculated using a period of time during which all of the individuals in the population are considered to be at risk for the outcome. It is sometimes referred to as the incidence proportion or the attack rate. Cumulative incidence is calculated by the number of new cases during a period divided by the number of people at risk in the population at the beginning of the study.

Attack rate is the proportion of exposed that become ill. Incidence rate is the number of new cases that become ill over a certain period of time.

The main difference between the total fertility rate and the rate of natural increase is that the total fertility rate measures the average number of children a woman is expected to have in her lifetime, while the rate of natural increase calculates the difference between the birth rate and the death rate in a population.

The difference between the coupon rate and the required return of a bond is dependent upon the type of bond. Junk bonds will have the biggest difference between its return and the coupon rate.
The difference between fixed and variable mortgages are that in a fixed mortgage, the rate can not change. In a variable mortgage, the rate changes with time.
