Kaplan Meier Survival

Modelling analyses are new to Ranges 9. Kapan Meier survival analysis is a method for estimating survival or dispersal rates that is convenient for data from radio-tagging. The Kaplan-Meier approach (Kaplan & Meier 1958), as described for radio-tracking by Pollock et al. (1989), is provided as a first survival estimation technique. Its interval-based estimation procedure adapts well to the asynchronous (staggered) entries and departures for unknown reasons that are typical for groups of radio-tagged animals.
