We drew up 2 X 2 tables for each
age group. We wanted to estimate the number in the bottom right corner of the table. How would you do that? If we assume that the ratio: “Notified by NHSCR? - No” / “Notified by NHSCR? - Yes” is the same for cases that are and are not notified by other sources, then the number of unknown cases can be estimated from: ? = 86 * (11 / 215) = 4.4 Learn more about capture-recapture methods |
