More Than Two Visits
The literature on the analysis of capture-recapture studies has blossomed since the early 1990s. There are very elaborate statistical models available for the analysis of these experiments. A simple model which easily accommodates the three source, or the three visit study, is to fit a Poisson regression model. Sophisticated mark-recapture models can be fit using Recapture, a package of the Open Source R programming language, or specialized programs such as MARK or M-SURGE. Other related methods which are often used include the Jolly-Seber model (used in open populations and for multiple census estimates) and Schnabel estimators (described above as an expansion to the Lincoln-Petersen method for closed populations). These are described in detail by Sutherland.
