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 =

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

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.

What is the difference between ROC curve and gains/lift chart? how to do them in R? Thanks. -- View this message in context: http://www.nabble.com/ROC-curve-and-gains-lift-chart-tp25083979p25083979.html Sent from the R help mailing list archive at Nabble.com.

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

Hello everybody, I met a problem when I configure the samba for our company. The case is, 1. We have to use Windows Domain to authenticate the user. 2. Only a few domain users can access the samba server. 2. We wanna all the allowed domain users are mapped to 1 unix userid: checkpoint. The Window Domain auth is working perfect. And if we created the unix id same as the domain users,

Hi, See below I reply your message for <https://stat.ethz.ch/pipermail/r-help/2008-April/160966.html>[R] predict.glm & newdata posted on Fri Apr 4 21:02:24 CEST 2008 You say it ##works fine but it does not: if you look at the length of yhat2, you will find 100 and not 200 as expected. In fact predict(reg1, data=x2) gives the same results as predict(reg1). So I am still looking for

Server - HPUX 11.31 Clients - WIN7 WIN10 After upgrading my versions to 4.9.0.0 I've noticed that we're unable to connect to our AD joined SMB HP-UX Server any longer. Could someone tell me where to begin digging in release notes between 3.6.6-4.9.0.0 to find out what changed in the smb.conf file that would be causing our problems? Here's a somewhat similar .conf output global]

Hi, A commonly used set of graphical techniques to compare the predictive capabilities of different potential models in the data mining area are known as "lift charts". I was wondering if any one has written such a function in R, and if they had, could they let me have a peak at their code.

I'm unintentionally allocating too much space on the stack by using `alloca` inside a loop. To fix this I will do my `alloca` outside of the loop itself.  I'm wondering if there is a way for this to be automatically done: given alloca a function scope, rather than loop scope. I'm curious also, since this actually allocates each time in the loop, is there a way to say the stack

Hi all, I'd like to do cross-validation on lm and get the resulting lift curve/table (or, alternatively, the estimates on 100% of my data with which I can get lift). If such a thing doesn't exist, could it be derived using cv.lm, or would we need to start from scratch? Thanks! -- Eric Siegel, Ph.D. President Prediction Impact, Inc.

In RHEL-based distros, the provided icons have (obviously) different sizes than the RHEL ones, used in icon_rhel as reference. Since 100K should be a reasonable threshold for avoid keeping a per-distro list of limits, just use it as only size limit. --- src/inspect-icon.c | 11 ++++------- 1 file changed, 4 insertions(+), 7 deletions(-) diff --git a/src/inspect-icon.c b/src/inspect-icon.c index
