[Biomod-commits] Predictive performance in Ensemble.Forecasting()

[Wilfried Thuiller]

Hi Jonathan,
> I've read the Manual carefully. Still, I am not sure about the predictive performance given by the function Ensemble.Forecasting() when the argument Test=TRUE.
> Probability values derived from different consensus methods are compared with the data input for a given species using the ROC-curve. But, is the entire data set considered now or the testing data that were kept in memory somewhere? Thanks for an answer. Cheers Jonathan

Yes, you're entirely right.
We might indeed think to test it with the testing data. Would be much more accurate actually...  good point. I'll think about that.

Wilfried
