Hi, I am trying to model credit risk data using decision trees. Since the number of defaulters is less compared to non-defaulters (defaulters around 10%), we have the class imbalance problem. Consequently, the confusion matrix shows that the number of misclassified non-defaulters is large. Classifying a defaulter as non-defaulter is more expensive. How does one include this information

Hi, I think this is a very simple situation but I need help in this matter asap. I have a linux m/c running samba-2.0.2. This is on a n/w controlled by a Win NT PDS. But I don't want Win NT to do the login authentication. So i've configured samba to act as a file server doing the login checking but i've not included it in the NT domain. Is this correct? And if so how do I configure my

Hi I have samba 2.0.2-1 running on a linux box having kernel 2.0.36. I have an NT 4 sp3 having a domain name RNDENT. I have included the linux box into the NT domain. I also have the smbpasswd file and cerated samba users. Samba is configured in such a way that even if NT is down samba takes over as the PDC and authenticates users. If NT is up, the server manager in NT shows the linux box as

Dear R gurus, I am trying to work out the problem given in Nested design - Montgomery - Design of Experiments p.561 I have attached a pdf of the data as well the anova table. It is a mixed model with Supplier as fixed effect and batches within the supplier as random effects. I am able to work out the error stratums as below using aov. Which agrees perfectly with the book example

Hi All, Can anybody tell me how can i type regional languages like Hindi, Tamil, etc in a text area using virtual keyboard or something. Otherwise like Orkut, if I written something in English, it should automatically convert into selected language. Any plugin or gem is there to do this.

I have been using random forest on a data set with 226 sites and 36 explanatory variables (continuous and categorical). When I use "tune.randomforest" to determine the best value to use in "mtry" there is a fairly consistent and steady decrease in MSE, with the optimum of "mtry" usually equal to 1. Why would that occur, and what does it signify? What I would

Dear R-helpers, I'm working on mass spectra in randomForest/R, and following the recommendations for the case of noisy variables, I don't want to use the default mtry (sqrt of nvariables), but I'm not sure up to which proportion mtry/nvariables it makes sense to increase mtry without "overtuning" RF. Let me tell my example: I have 106 spectra belonging to 4 classes, the

Dear Researches, I am using RF (in regression way) for analize several metrics extract from image. I am tuning RF setting a loop using different range of mtry, tree and nodesize using the lower value of MSE-OOB mtry from 1 to 5 nodesize from1 to 10 tree from 1 to 500 using this paper as refery Palmer, D.

Hello R Gurus, I am perplexed by the different results I obtained when I ran code like this: set.seed(100) test1<-randomForest(BinaryY~., data=Xvars, trees=51, mtry=5, seed=200) predict(test1, newdata=cbind(NewBinaryY, NewXs), type="response") and this code: set.seed(100) test2<-randomForest(BinaryY~., data=Xvars, trees=51, mtry=5, seed=200, xtest=NewXs, ytest=NewBinarY) The

Dear R-users, While making a prediction using the randomForest function (package randomForest) I'm getting the following error message: "Error in predict.randomForest(model, newdata = CV) : No forest component in the object" Here's my complete code.
