Hello everyone I am trying to find a way to test for spatial autocorrelation in Maxent models. From my understanding, this should be tested on the residuals of the model. So far I have only been able to test for Moran I test on the prediction resulting raster using the package ELSA. However, I think I am just testing Moran on the prediction values this way. Would that be enough or ok? I will appreciate if someone can give me some insight. Best wishes Diego
Spatial autocorrelation in Maxent models

Dear Diego, Yes, you calculated the spatial autocorrelation of the predicted values in this way, which is not too informative and intresting. Autocorrelation of the residuals is what you need. If you subtract the predictions from the observations (using the simple raster algebra or raster::calc()), you can calculate Moran's I (or any other spatial autocorrelation measure) of the residuals.
