It means that Suppose that a random event occurs, on the average, once every 100 years. The risk (or probability) that this event will occur in any 10-year period is:
Risk = 1 - [1 - 1/(R.I.)]n
= 1- [1 - 1/(100)]10
= 1 - [0.99]10 = 0.096 (or 9.6%)
Similarly, we can calculate the cumulative risks for various other time periods (for R.I. = 100):
TIME PERIOD (n) [1 - 1 / (R.I.)]n CUMULATIVE RISK 20 years 0.82 18% 25 years 0.78 22% 69 years 0.50 50% 100 years 0.37 63%Death
Cumulative Frequency
it means your prizes will be chosen for you.
Cumulative is the correct spelling.It is an adjective, and means: "increasing or increased in quantity, degree, or force by successive additions: the cumulative effect of two years of drought."
I've occasionally seen "cumulative frequency" shortened to the word "cume".
Cumulative risks are risks that increase with each added risk.
No, they need not be.
Yes.We do include vaccinated population from population at risk calculating cumulative incidence.
the answer is related risks that increase in effect with each added risk.
what dose cumulative force mean
Death
comulative risks are related risks that increase with each added risk. An example is using a cell phone while driving.
Here is an example: Fire fighters face many hazards. Explosions, fire, toxic inhalations, etc. The cumulative risk of being a fire fighters is immense.
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
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.
