Description of the Project:
In a health study to investigate an
epidemic outbreak of disease (spread by mosquitoes), individuals were randomly sampled
within two sectors in a city to determine if the person had the disease under study.
The response variable y was coded 1 if an individual had the disease, and 0 if not.
The three predictor variables included in this study were:
 | age (quantitative variable)
|
 | socioeconomic status of household
(categorical variable) - three levels:
|
 | sector within city (categorical
variable) - two levels:
 | sector 1
|
 | sector 2
|
|
NOTE: It is expected that the upper
socioeconomic class will have the lowest disease rate among the three classes.
Hence, it is chosen as the reference class (i.e. The class for which indicator
variables x2 and x3 are coded 0) |
