a. Use age as an explanatory variable to create a Poisson regression model for the incidence rate of skin cancer among women in Dallas–Fort Worth.
b. Is age a significant predictor of the incidence rate of skin cancer among women in Dallas–Fort Worth?
c. Using only the data from Dallas–Fort Worth how does the risk of cancer for women aged 50 years relate to the risk for women aged 40 years?
d. Create a model using both locations (Minneapolis–St. Paul and Dallas–Fort Worth), age, and an interaction term to estimate the incidence rate for skin cancer. Does one city have a higher risk of non-melanoma skin cancer for women than the other? Is there an interaction between age and location?
