Howdy! Could somebody point me to some good introductory readings about data mining and descriptive data analysis? I'm a psychologist and a couple of times I realized that some things just don't appear in psychological literature, e.g. I've never seen a box plot anywhere in psych journals so I'm not familiar with them. The R help function is great when it comes to explaining

Hi, Are you guys interested in implementing if-conversion as a GSoC 2015 project? Last year, I did a literature review about approaches of if-conversion and the if-conversion in LLVM. This was the undergraduate thesis of my bachelor degree. It seems that, the if-conversion used in LLVM is a very simple approach instead of following the literature. So I want to implement the approaches in the

Hello, I am Mudit Raj Gupta, fourth year student of M.S. (Hons.) Chemistry and B.E. (Hons.) Electronics and Instrumentation at BITS-Pilani ( http://www.bits-pilani.ac.in/). I am interested in *Machine Learning and Computaional Intelligence*. I have an interest in implementing various existing algorithms and developing modified/new algorithms related to machine learning and computational

Hi, all On the website, it says "... There are several well-known ways to do this in the literature. LLVM uses a SelectionDAG based instruction selector." I want to know more about the SelectionDAG, maybe the one which guide LLVM SelectionDAG implementation. Any suggestion? Thanks!

Hi All, theoretically, I should be able (with proper proxy setting and IP address) to connect and perform literature database searches, such as in the ISI Web of Science, with R. I can imagine this working nicely with the RCurl package. I am pestering the list to ask if I missed a certain package in the Task View or to see if anyone had a similar idea and has already written such code.

Dear all, I am a statistician doing research in QSAR, building regression models where the dependent variable is a numerical expression of some chemical activity and input variables are chemical descriptors, e.g. molecular weight, number of carbon atoms, etc. I am building regression models and I am confronted with a widely a technique called Y-RANDOMIZATION for which I have difficulties in

Hi all, I am trying to fit a logistic regression for a bivariate response using five independent variables in a stepwise procedure. My outputs look okay but does any one know (or is there any literature on) how the confidence intervals are calculated for the reported odds ratios..? Thanks! [[alternative HTML version deleted]]

Hello everyone, Very quick question: How should I cite the use of R in a publication ? Thanks in advance. Sebastien

Hi, in order to understand the Ogg Vorbis decoding algorithm, do you recommend any document/book/www? I have read those on the web page but look for something more detailed..

This is a more general statiscal question, not specific to R: As I move through my masters curriculum in statistics, I am becoming more and more attuned to issues of model fit and diagnostics (graphical methods, AIC, BIC, deviance, etc.) As my regression professor always likes to say, only draw substantive conclusions from valid models. Yet in published articles in my field (medicine), I

Dear R experts, I had a question which may not be directly relevant to R but I will be grateful if you can give me some advices. I ran a two-level multilevel model for data with repeated measurements over time, i.e. level-1 the repeated measures and level-2 subjects. I could not get convergence using lme(), so I tried MLwiN, which eventually showed the level-2 variances (random effects for

Dear R list As suggested by Prof Brian Ripley, I have tried to read acf literature. The main problem is I am not the statistician and hence have some problem in understanding the concepts immediately. I came across one literature (http://www.stat.nus.edu.sg/~staxyc/REG32.pdf) on auto-correlation giving the methodology. As per that literature, the auto-correlation is arrived at as per following.

OK, Let me describe. There is nothing wrong with if-conversion in LLVM. The algorithm implemented in LLVM can handle the if(???){do something} and if(???){do something}else{do something else} case very well. But it can handle complicated case like when there are a lot of gotos in the program. The more systematic way to do if-conversion is based on Hyperblock [Scott A. Mahlke et al 1992]

Dear R-helpers, i have the following situation: i have a bunch of y=b0 + b1*x from different studies, and want to estimate a "general" y=f(x). I only have the b0,b1's and R-squareds. Should i weigh the separate equations by their R-squared? thanks Remko ^'~,_,~'^'~,_,~'^'~,_,~'^'~,_,~'^'~,_,~'^'~,_,~' Remko Duursma, Ph.D. student

Dear list, I hope the topic is of sufficient interest, because it is not R-related. I have N=100 yes/no-responses from a psychophysics paradigm (say Y Yes and 100-Y No-Responses). I want to see whether these yes-no-responses are in line with a model predicting a certain amount p of yes-responses. Standard procedure would be a one-sample binomial test for the observed proportion, chi?(1 df) =

Dear Sir, I am comparing two samples using wilcox.test in R. Literature appears to describe mann whitney u test as the most appropriate test to use on my data. is the wilcox.test function equivalent to mann-whitney u? Is there a way to gain the U-value as apposed to the W-value in R? Thank you

Hi AlL, I ahve this problem that my objective function is discontinous in the paramaters and I need to use methods such as nelder-mead to get around this. My question is: How do i compute standard errors to a problem that does not have a gradient? Any literature on this is greatly appreciated. Jean,

Hi It is preferable to echo your posts to r-help, you usually get more answers and some definitelly superb to mine.
