Figure 1

Observed marginal incidence λobs(a|x)×1000 of prostate cancer, λobs(a|x)=C(a, x)/P(a, x), by age a and year of diagnosis x+a. The empirical estimate corresponds to the ratio of the count of observed cases C to the size of the population P at risk measured in thousands. Single age-year bins are used. Figure is based on SEER data (http://seer.cancer.gov/).
