Hi!   I have been reading lots of queries regarding logistic regression as well as Credit scoring model and the related replies, which I must admit are full of wisdom and help us to understand where do we stand. The contributions of Frank E Harrell Jr, etc are invaluable. Incidentally I am also trying to work on Credit scoring model and initially I tried to use the multiple regression etc. and now

Hi! I am a post graduate in Statistics. I want to learn R language, but am very confused as to how to begin systematically. I need to learn R language from Statistics point of view e.g. I need to fit distributions to data or run regression analysis etc. No doubt there are so many articles available on internet. But can someone guide me as to how do I begin and go on improving myself

Does anyone know if there is a package or other method of reading Genstat files directly into R. Genstat isn't listed in the foreign package. Many thanks, Graham [[alternative HTML version deleted]]

Dear List, I couldn't find any package that performs the "weight of evidence" of predictors (a transformation usually performed in credit scoring applications). Is there any that you know? Thanks, Axel. [[alternative HTML version deleted]]

Hello Colleagues, I programmed in SAS for 3 years and would like to switch to a not so costly software product. Hence I started to evaluate R, and my first test look promising. However I have some question: 1. Is it possible to query R files by SQL internally on data frames (not on a database) and how is the syntax (I have the RODBC package installed). I would like to extract year, Quarter,

Hi netters, I want to learn a decision tree from a series of instances (learning data). The packages tree or rpart can do this quite well, but the scoring functions (splitting criteria) are fixed in these packages, like gini or something. However, I'm going to use another scoring function. At first I wanna modify the R code of tree or rpart and put my own scoring function in. But it

Hi, I was wondering if I can have some advice on the following problem. Let's say that I have a problem in which I want to predict a binary outcome and I use logistic regression for that purpose. In addition, suppose that my model includes predictors that will not be used in scoring new observations but must be used during model training to absorb certain effects that could bias the

From some papers the authors mentioned that some experiments of the automated essay scoring study are using the package of the R open source software. I am a new learner of R and I would like to know which package of R can be used to serve this purpose and how to do then. Grateful if you could give me

Hi all! I'm getting starting with LLVM, and I'm creating a new cross-platform programming language LLVM-based with a Standard Library POSIX-based. The language has sintatic sugar of Object Pascal and Ruby. My doubt is if LLVM is compatible with AMD (e.g. Fusion), allowing so that my StdLib can be used to create Games, in future...
