prediction intervals (alpha and beta) for model average estimates from binomial glm and model.avg (library=dRedging)
Hi all, I was wondering if there is a function out there, or someone has written code for making confidence intervals around model averaged predictions (y~á+âx). The model average estimates are from the dRedging library? It seems a common thing but I can't seem to find one via the search engines Examples of the models are: fit1 <- glm(y~ dbh, family = binomial, data = data) fit2 <-

comparisons
I converted the 128kbps tom.mp3 file into a .wav and then used oggenc -m 2 to laterally encode it to 128kbps tommy.ogg format. I noticed that it gets very close to the size of an mp3, great job guys. Then I got to thinking that maybe it could be compressed further with gzip so I tried it. I also gzipped the mp3 to compare and it looks like the mp3 gzips better but gzipping the ogg file will get

ISDN30 card for UK : sanity check
We will be connecting our Asterisk server to ISDN 30 and intend using the Sangoma A101 card. The install location is in London (UK). Sangoma card at Voipon http://www.voipon.co.uk/sangoma-a101-pri-isdn-card-p-132.html?gclid=CI32vJz22I0CFQXklAodIgjHaA I would be grateful to hear if this is the right choice of card. Usage reports would be helpful. Regards Rory -- Rory Campbell-Lange

philosophy of cvs/git/wine-patch
Hi, Since 4 weeks, I'm looking at the different ways to obtain the lastest wine. I want to test it and try to find problems with the poor few games i have, in order to help developers and wine development too :) But I don't really understand the differences between cvs, git and wine-patches. I think that cvs and git are the same wine "version". But for wine-patches, i

Philosophy behind converting Fortran to C for use in R
Here are three reasons for converting Fortran code, especially older Fortran code, to C: 1. The C-Fortran interface is not standardized. Various Fortran compilers pass logical and character arguments in various ways. Various Fortran compilers mangle function and common block names in variousl ways. You can avoid that problem by restricting R to using a certain Fortran compiler, but that can

tc philosophy, will this work?
Correct me if I''m wrong, I just want to help my friend who needs a tc solution with fairness to hosts on a 512K/s DSL line, but few of them should be restricted to 64K/s I thought about htb + esfq (sfq with ip based fairness, not connection) parent class with CEIL=500Kbit (no RULE? see *1) and attached esfq to this parent class, now child class with CEIL=64Kbit and RULE=10.0.0.1

Musings about Rails and Logging and philosophy
As a perpetual Rails dabbler, I make an awful lot of typical beginner mistakes. And the logs are always either too verbose or too sparse to help me. And it started me thinking. I came from one of the largest production OLTP systems in the world, and the one thing that helped us manage troubleshooting in both development and production was extensive, obsessive, flexible logging. Every operation

include/exclude: I miss the point
Hi all, I thought I understand how include/exclude and their precedences work (I read the user guide about this), but I seem to miss something. I have 2 questions about this, separated by ====== Question 1: -------------- I want to exclude the "hidden" directories except some sub-dirs or files: .mybackup and its files) and the mozilla firefox bookmarks folder and its contents

VM Philosophy 101 - How many and for what?
We are at the stage, finally, where we are prepared to deploy public facing VM guests. Now we have to answer these questions: How many guests in total should we contemplate and what services are placed on which guests? My question comes down to whether it is considered advisable to run the primary DNS and IMAP, or indeed all services, on separate vm guests; or should we continue, more or less,

dredge solely offset models in MuMIn
hello everyone, I'm modelling in lmer an average chick weight defined as "Total.brood.mass ~ offset(chick.number), with three fixed and two random effect. Next, I want to use function dredge from MuMIn package for model averaging. Not sure why, but in consequence the offset variable is treated as a predictor, so I get a table that mixes models with and without that offset term (the first

Error message in dredge function (MuMIn package) with binary GLM

MVC Philosophy
My directory browsing app shows lists of file. If the item is a folder, show a folder icon and link to the action that shows directory contents. If the item is a graphics file, show a thumbnail and link to a larger view. If the item is a non-graphics file, show an appropriate icon and stream the file if the link is clicked. The controller creates an array of arrays of items in the current folder,

Error running MuMIn dredge function using glmer models
Dear list, I am trying to use MuMIn to compare all possible mixed models using the dredge function on binomial data but I am getting an error message that I cannot decode. This error only occurs when I use glmer. When I use an lmer analysis on a different response variable every works great. Example using a simplified glmer model global model: mod<- glmer(cbind(st$X2.REP.LIVE,

Double render/redirect philosophy
Ok, I think I understand why RoR will flag an attempt double render in an action. What I don''t understand is the philosophy of render and redirect_to. Specifically, why isn''t a return implicit in both those methods? Or, I guess, more to the point ... what are the advantages of writing code in the action after a render/redirect_to? -- Posted via http://www.ruby-forum.com/. --

Programming Concepts and Philosophy
I am wondering if people on the list could recommend books that they have found helpful about programming concepts and style? I often find that students write R programs by copying existing code but could really benefit from the understanding of more general programming ideas. An example would be to avoid writing functions which attempt to modify their parameters. Another principle would be

Package MuMIn (dredge): Error in ret[, ] <- cbind(x, se, rep(if (is.null(df)) NA_real_ else df, : number of items to replace is not a multiple of replacement length.
Hello R community, I am attempting to run multiple logistic regressions (multinomial, via package 'nnet'), with Automated Model Selection (dredge, package 'MuMIn'). The aim is to reduce the number of predictor variables by assessing relative performance of each variable, which can be done in a coarse fashion using the Automated Model Selection option in package 'MuMIn'

Philosophy behind converting Fortran to C for use in R
Hello. This is not a question about a bug or even best practices; rather I'm trying to understand the philosophy or theory as to why certain portions of the R codebase are written as they are. If this question is better posed elsewhere, please point me in the proper direction. In the thread about the issues with the Tukey line, Martin said [1]: > when this topic came up last (for me) in
