Hi All, I am looking for a reference that explains how the randomForest function in the randomForest package uses the classwt parameter. Here:
http://tolstoy.newcastle.edu.au/R/e4/help/08/05/12088.html Andy Liaw suggests not using classwt. And according to: http://r.789695.n4.nabble.com/R-help-with-RandomForest-classwt-option-td817149.html it has "not been implemented" as of 2007. However it improved classification performance for a problem I am working on, more than adjusting the sampsize parameter. So I'm wondering if it has been implemented recently (since 2007) or if there is a detailed explanation of what this unimplemented version is doing. Thanks!
