Hi, I am trying to do some predictive modeling around attrition and want to split the dataset into test and train (80:20) and keep the ratio of attritees:non attrites same. In my dataset the attrition indicator is coded as 0(for non-attritees) and 1 (for attritees) and I want to keep the ratio of 0's to 1 similar. I apologize for this trivial question but this is my second week with R.

Hi, I am stuck with creating a conditional categorical variable in R If my dataframe data_2 has 3 variables A,B,C I want to create variable D which would be something like : data_2$D <- ifelse(data_2$A < data_2$B & promotion_ind =="N",1,0), this throws up an error "In Ops.factor(data_2$A,data_2$B) : < not meaningful for factors I have tried converting the

Dear colleagues, New versions of "R for Beginners" in French and in English are available on CRAN in the Contributed Documentation section. The document is now nearly 60 pages long, and has been completely revised. The description of "objects" and of data manipulation has been completely re-written. The section on graphics has been particularly extended, and includes now an

Hi, I have a logit model built in R which I am trying to validate . Could you please help me with creating lift charts and area under ROC for the same. I am trying to use package ROCR The indicative code for this is : newlogit3<- glm(Attrition_ind ~ Time.in.AXP+ Age +as.factor(Increase.in.Rating.in.Current.year) +as.factor(Below.Market.Merit.Budget)+as.factor(Drop.in.AIA)

Hi, I'am using the sentient analysis available in "R2.15". Now the challenge that I'am facing is that the Naïve Baye's has an inbuilt list of 6500 words in which it has been trained. So my question that can I increase the number of words on which this algorithm is trained? In case i can increase the list can someone tell me the procedure? Regards Nalin American Express

Ralph, Conrad, Now that we have ROE as a means to describe a multi-track ogg file - i.e. a means to author Skeleton - I assume this is supposed to describe how we map ROE information into Skeleton through the use of fisbone message header fields, right? In this case I wonder if you have gone over all the current ROE spec and made sure that all this information is either in ROE or easily

Hi everyone, I am trying to validate a logistic model built in R. Not my version of R is 2.12 and I cannot install ROCR. I have gone to a point where I have the predicted values using the code: pred1 = predict(trainlogit1,testdata_1, type = "response") How do I proceed from here? Is there another way in which I can plot lift charts? My model output is: Call: glm(formula =

We have new drafts of CMML 4.0 as a text codec and ROE as an xml stream abstract, subsuming the authoring support in CMML 3.1 and earlier. Another thing we talked about at LCA is a how to specify relationships between the various streams in Ogg so that a server, muxer or player can make intelligent decisions about the contained tracks. The general idea is to use the (http-style) Message
