In tidysdm: Species Distribution Models with Tidymodels

Model specification for a MaxEnt for SDM

Description

This function returns a parsnip::model_spec for a MaxEnt model to be used in Species Distribution Models.

Usage

sdm_spec_maxent(..., tune = c("sdm", "all", "custom", "none"))

Arguments

...

parameters to be passed to maxent() to customise the model. See the help of that function for details.

tune

character defining the tuning strategy. Valid strategies are: "sdm" chooses hyper-parameters that are most important to tune for an sdm (for maxent, 'feature_classes' and 'regularization_multiplier') "all" tunes all hyperparameters (for maxent, 'feature_classes' and 'regularization_multiplier', the same as with tune = "sdm") "custom" passes the options from '...' "none" does not tune any hyperparameter

Value

a parsnip::model_spec of the model.
