We are planning to evaluate the quality of our cancer registry data for its completeness by using 3 sources of data, is there any one who would like to help us in capture-recapture analysis?
I think the main problem with capture-recapture methods is meeting the necessary assumption of the heterogeneity of mixing in the population, so that the recapture is independent of the first capture.
You need to make sure you understand the underlying assumption of capture-recapture. In the R library there are few packages that will help you to do the analysis.
