Background models need multiple replicates #2

Open jcoliver opened 6 years ago

jcoliver commented 6 years ago

bioclim models with pseudo-absence points can demonstrate considerable dependence on which points are actually sampled as background (i.e. "absence") points. Need to run multiple replicates of the models, re-sampling the pseudo-absence points between replicates. Combine the results:

for probabilities, do summation divided by number of replicates
for threshold, make composite with probability of presence (based on individual models' threshold) in ~90% of models

Is this critical?

Not critical for now, but wouldn't hurt to mention it in documentation and direct users to additional resources.
