Thanks, Max. Yes, I　did some feature selections in the training set. Basically, I selected the top 1000 SNPs based on OOB error and grow the forest using training set, then using the test set to validate the forest grown.
But if I do the same thing in test set, the top SNPs would be different than those in training set. That may be difficult to interpret. -- View this message in context: http://r.789695.n4.nabble.com/Random-Forest-Cross-Validation-tp3314777p3320094.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
