Subject: error in random forest
Hi,
I get the following error when I try to predict the probabilities of a
test sample:
Error in predict.randomForest(fit.EBA.OM.rf.50, x.OM, type = "prob") :
New factor levels not present in the training data
I have about 630 predictor variables in the dataset x.OM (25 factor
variables and the remaining are continuous variables). Any ideas on
how to trace it?
Thank you,
Nagu
