Datasets
Here are the datasets used in the Ecological Modeling paper referenced above:
- - the coverages we used in modeling.
- - the raw ipcc data, as dowloaded from the . Also the annual and monthly variables we used for our study, extracted from the raw ipcc data and converted into world-wide coverages in .asc format.
- - the training and testing sample localities we used.
Main changes in Version 3.3
- Replicated runs added, to allow cross-validation, bootstrapping and repeated subsampling. After a replicated run, a web page is made that analyzes and combines the results of the individual runs.
- Clamping pictures have changed. When projecting, the picture showing the effect of clamping now simply shows the difference between the predictions with and without clamping.
- Parameters are treated more uniformly, and many more are exposed in the Settings window and described in the Help window.
- Bug fixed in handling of bias files.
- The feature type buttons have a slightly different meaning, with "auto features" choosing a subset of the selected types. This allows you to limit the feature types used by auto features.
More efficient memory usage, to avoid memory problems with large grids. - Pictures of predictions are now created by default.
- Duplicate presence records are now removed by default.
Projection onto SWD-format files and writing of background predictions both preserve x and y coordinates of points. - The html output now gives the command line with all flags needed to repeat a run.
- A limited API for calling Maxent from other Java code.
