A cumulative frequency polygon has straight lines connecting the points. A normal cumulative frequency diagram uses a smooth curve to join the points.

What is the difference between discrete and cumulative distributions?
A discrete distribution is one in which the random variable can take only a limited number of values.

What is another name for cumulative frequency?
I've occasionally seen "cumulative frequency" shortened to the word "cume".
How do you find cumulative frequency?
By adding up the (one by one,) the frequency total in order to find the cumulative frequency, most commonly, you just then plot this on a cumulative frequency graph or box plot.
What is the formula to calculate cumulative incidence rate?
CI(t)=1-e-IR(t)*D
Difference between cumulative incidence and incidence rate?
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
What it cumulative incidence rate?
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.
