WebNov 1, 2024 · MaxEnt benefits from its ability to model presence-only (PO) data ( Elith et al., 2006; Phillips et al., 2006) and is thought to be robust to small sample sizes ( Kaky, 2024; Kaky and Gilbert, 2016; Wisz et al., 2008 ), as well as being able to model complex, non-linear relationships between the response variable and predictors ( Elith et al., … WebApr 1, 2024 · Maxent (Phillips et al., 2006) uses presence-only data to predict the distribution of a species based on the theory of maximum entropy. The program attempts to estimate a probability distribution of species occurrence that is closest to uniform while still subject to environmental constraints (Elith et al., 2011). WebTherefore, the Maxent model originating from the statistical mechanics (Jaynes, 1957) is very popular for accurately forecast-ing species distribution (Elith et al., 2006; Wang et al., 2010; Qin et al., 2024).
