SURPH is an analytical tool for estimating survival using release-recapture data as a function of environmental and experimental effects. These effects may apply to a population (such as ambient temperature) or an individual (such as body length). SURPH provides flexible modeling capability for selecting the most parsimonious models, and diagnostic reports and graphs for analysing data and selected models. Hypothesis testing can be done with Likelihood Ratio Test, AIC, or Analysis of Deviance.
