Disease Incidence

Overview

Disease incidence refers to a measurement of the number of incidences (onset) of a given disease in a region or population. That is, it counts the number of individuals that fell prey to a disease.

Often times it is useful to try to measure the relationship between the average number of incdience and a set of factors that are thought to possibly influence the size of the number.

An example would include the number of new cancer cases in a different regions with different levels of pollution.

Modeling Methods

• Poisson Regression - the Poission distribution is typically used to model count data, and the Poission regression is a method to measure the strength of the relationships in the data.
