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, 'mtry')
"all" tunes all hyperparameters (for maxent, 'mtry', 'trees' and 'min')
"custom" passes the options from '...'
"none" does not tune any hyperparameter
Value
a parsnip::model_spec of the model.
