Use the previous question to estimate the cancer rate at age 62 and at age 72 from the Poisson loglinear model for the CTR data. Compute the estimated cancer incidence rates as well. Calculate the difference between the observed cancer incidence rates from Table 8.1 and the estimated cancer incidence rates that you calculated. Are your answers consistent with the observed values in Table 8.1?
Table 8.1 Cancer cases and cancer incidence rates (CIR) by age group for the Bartlett€“Green Acres neighborhood of Randolph (BGA), 1964€“1984, and similar data from the Connecticut Tumor Registry (CTR), 1980€“1984.
