Hi, I use R at home, and am interested in using it at my work company (which is in the Fortune 100). I began the request, and our legal team has given some gruff about the open source license. Not boring you with the details here, but I used some info on gnu.org as a rebuttal, and someone at the company replied that the generalities of GNU GPL may differ from R's specific GNU GPL license,

Folks: The following has NOTHING (obvious) to do with R. But I believe that all on this list would find it relevant and, I hope, informative. It is LONG.

Dear R users, I am building a hierarchical model on a large data set. It can take quite some time to finish one fit, I was just wondering whether it is possible to store the fit object (the result) to a file for later (offline) analysis. thanks Julia -- View this message in context: http://www.nabble.com/how-to-store-lme-lmer-fit-result-tp19910951p19910951.html Sent from the R help mailing

We have a corpus of academic papers. Sometimes it happens that there is an academic controversy and one paper is a response or rebuttal to another paper. The name of the author of the first paper may appear many times in the second paper. So in light of this, how should we set our weight on the author field? Here is an example: http://www.nber.org/papers/w11215  in which the term

I came across this one: http://www.nysun.com/article/32787 which says that the violent death rate in Iraq (which presumably includes violent deaths from the war) is lower than the violent death rate in major American cities. Does anyone have any insights from statistics on how to interpret this?

Hello all. I'm currently working with mixed models, and have noticed a curious difference between the nlme and lmer packages. While I realize that model selection with mixed models is a tricky issue, the two packages currently produce different AIC scores for the same model, but they systematically differ by 2. In looking at the logLik values for each method, I find that they

Hi all, I am not a very proficient R-user yet, so I hope I am not wasting people?s time. I want to run a linear mixed model with 3 random factors (A, B, C) where A and B are partially crossed and C is nested within B. I understand that this is not easily possible using lme but it might be using lmer. I encountered two problems when trying: Firstly, I can enter two random factors in lmer but

Hello !! II'm trying to test for my fixed effects using an lmer with quasipoisson errors. Since my lmer model is corrected for overdispersion using this kind of errors, I should use during model simplification in my Anovas *F test *and not *Chi square test* to compare two models. So I write: > anova(model,model2,test="F") but R keeps performing a Chi square instead of the F
