"WebJun 3, 2024 · Nevertheless, MaxEnt is resistant to the influence of cross-correlated predictors (Elith et al., 2011) due to parametrization (the presence of λ coefficients for each F; see Sections 1 and 2). Therefore, even if the variables are strongly associated, this does not lead to noticeable distortions in the predicted spatial distribution. " - Elith maxent

WebNov 21, 2012 · In the absence of this information, MAXENT still provides maps of its logistic output; however, it arbitrarily assumes that probability of occupancy at an average site is 0·5 (Elith et al. 2011 ). As the occupancy probability at an average site is unlikely to be exactly 0·5, the resulting probability predictions will necessarily be biased.
