Extinction Date Estimation from Sighting Records R package EDE version 0.3.0 Infers the extinction of a species from a time-ordered record of sightings, collecting methods from the sighting-record and stratigraphic-range literature under one interface. Includes endpoint estimators (Robson & Whitlock, 1964; Strauss & Sadler, 1989; Roberts & Solow, 2003), frequentist persistence tests (Solow, 1993a, 1993b; Burgman, Grimson & Ferson, 1995; Solow & Roberts, 2003; Solow, 2005; McInerny, Roberts, Davy & Cribb, 2006; Jarić & Ebenhard, 2010), Bayesian models (Rout, Salomon & McCarthy, 2009; Caley & Barry, 2014), methods for sightings of uncertain reliability (Thompson et al., 2013; Jarić & Roberts, 2014; Lee et al., 2014; Brook, Buettel & Jarić, 2019; Kodikara et al., 2020, 2021), models combining records and surveys (Thompson et al., 2017, 2019), and confidence intervals on the end-points of fossil ranges (Marshall, 1994, 1997; Weiss & Marshall, 1999). Every method is tested against the published examples of its source paper and returns a common result class; persistence tests are inverted to give one-sided upper confidence bounds.
