The following download uses a set of simplified sight-resight history frequencies for a sample of dogs in a city block to estimate what fraction of the dogs that roam in that block are seen on any one count. A sample of distinctive dogs is identified during the first count and resights of those dogs on a second and third count recorded. For each identified dog the four possible histories are thus: seen on both the second and third counts; seen on neither the second nor the third count; seen on the third but not the second count; seen on the second but not the third count. The four frequencies are entered on a screen and an estimate of the fraction of dogs seen on any one count returned along with an estimate of the fraction of dogs that are permanently visible.
