...1) are a general class models that predict count data (i.e. the number of individuals; Warton and Shepherd 2010, Aarts et al. 2012, Fithian and Hastie 2012, Renner and Warton 2012, Royle et al. 2012)....

...These two sampling assumptions (individuals vs grid cells) can lead to similar results when presences are spatially sparse but are incompatible when multiple counts are likely to occur per grid cell (Renner and Warton 2012)....
[...]
...This approach corresponds to treating MaxEnt as a traditional statistical model (cf. Renner and Warton 2012)....

...Furthermore, Renner and Warton (2012) note that the assumption of spatial independence of PO samples may be frequently be violated, but that inhomogeneous Poisson point process models can remedy this to some extent....

...(2) is a discretized approximation to more general class of inhomogeneous Poisson point process models that treat the landscape as continuous (Warton and Shepherd 2010, Chakraborty et al. 2011, Fithian and Hastie 2012, Renner and Warton 2012)....

...Because Maxent is an IPP, standard generalized linear modeling software can be used to fit Maxent models via Poisson regression (Renner and Warton 2013), or even more conveniently, using standard logistic regression (Fithian and Hastie 2013)....

...More recently, it was noted that the exact same maximum likelihood exponential model can be obtained from an inhomogeneous Poisson process (IPP) (Aarts et al. 2012, Fithian and Hastie 2013, Renner and Warton 2013)....

...Recent work has demonstrated equivalency between the MAXENT algorithm and loglinear generalized linear models (Renner & Warton 2013), as well as close links to inhomoge- neous Poisson process (IPP) models (Fithian & Hastie 2013)....

...More generally, results based on the tuning approach should be compared with model selection based on information criteria (e.g. the AIC corrected for small sample size, AICc; Warren & Seifert, 2011) and generalized cross validation (GCV), which is similar in intent (Renner & Warton, 2013)....

...…as the Akaike information criterion (AIC) or nonlinear generalized cross validation (GCV) – which each penalize increasingly complex models – but recently proposed use of such approaches for ecological niche models requires further empirical testing (Warren & Seifert, 2011; Renner & Warton, 2013)....

...Our analysis will consist of four steps: (1) determine the appropriate spatial resolution for analysis; (2) assess whether a Poisson point process model is appropriate; (3) estimate the LASSO parameter (Tibshirani, 1996) for regularization; and (4) compare results with a MAXENT model....

...Alternatively, some datadriven criterion could be used to try to choose a λ which optimizes predictive performance (Tibshirani, 1996; Fu, 2005; Zou, Hastie, and Tibshirani, 2007)....

...Prior to applying the LASSO to point process models, variables were standardized to have mean 0 and variance 1 as in Tibshirani (1996), such that the LASSO penalty was applied to standardized coefficients....
