randomForestSRC individual tree predictions #1

Open MNRiverEcologyUnit opened 7 years ago

MNRiverEcologyUnit commented 7 years ago

How can the individual tree predictions, OOB and or inbag, be accessed?

ehrlinger commented 7 years ago

Individual tree predictions are not especially useful, as the predicted value is the ensemble of all trees. You can get the OOB or inbag ensemble predictions using the predict.rfsrc function.

Thanks for getting back so quick. I’m new to the random forest technique and was trying to think of a way to provide some error around the prediction. I was thinking I could use the individual predictions to get a nonparametric confidence interval, but perhaps using the sqrt of the error rate would be a better option. Thanks again.
