OTU feature rank #37

Open kdiverson opened 11 years ago

With default parameters too many of the low abundance OTUs are being ranked as very important. Changing the stdthreshold to a higher value like .5 gets rid of these OTUs. Suggest implementing a different default parameter or implement mean decrease in accuracy or gini index for feature selection similar to the R implementation.
