Simply Tagging has the following estimation methods for closed populations:

Model M0:        Constant probability of capture

Model Mt:        Maximum likelihood Schnabel census (Petersen-Lincoln index if samples = 2)

Model Mt:        Chao method

Model Mh:        Individual variation in probability of capture

Model Mb:        Behavioural changes following capture

Model Mth:        Temporal changes in catchability and individual heterogeneity


For open populations Simply Tagging offers both a full Jolly-Seber analysis and a reduced model in which probability of capture and survival are assumed to be constant over the period of the experiment.


Simply Tagging also offers a data simulation module.
